Okay, I'm going to start.
10. Rapid Blaster
Now ya see, Rapid has always held a special place in my heart. From the moment I first used it, I've always liked it. It started in it's first kill challenge (where I try to get a good k/d with a weapon in Turf War, going up to 70 kills or 50 for chargers (that's important to know b/c I like a lot of these weapons based solely on the Kill Challenge)), where I was constantly joking about how it was the best weapon in the game back when Rapid wasn't that great of a weapon (I'd say about 3-4 weeks before it received its amazing buffs). But at the same time, I was also saying that it was actually the worst weapon in the game, so I was ultimately (yet intentionally) contradicting myself. And in the midst of all of it, I was getting off some crazy stuff. Double directs and ink mine kills, most notably, but even the indirect shots killed, and I was satisfied. I don't know... something about the Rapid Blaster just clicked with me, and I've loved using it for fun to this day. I don't use it much anymore, however, so that's why it's #10.
9. Cherry H-3 Nozzlenose
Cherry H-3 is one of those weapons that I just love running Tenacity + special charge + Le Soccer Cleats on. Just having so much special charge and getting a bubble so often with such a long range weapon feels so great. A lot of people don't like invincibility specials, and personally my only real gripe is with Bubbler. Kraken has limits to it that just don't make it as good, but it's still a lot of fun to use. Same with Bubbler. I think the thing that really makes me like Cherry H-3 is all the protection, because I love using Bubbler, and I absolutely love walls (used to main 96 Deco back in the day, until I realized I'd always be tr4sh w/ it). It's just a fun weapon to mess around with, and grinding up invincibilities is just fun to me.
8. Custom Dual Squelcher
I've always said that people should give Custom Dual more of a chance since it can support in ways that no other shooter with its range can. I've said it's better than the normal Dual for that reason, but now that I look at it, regular Dual has nades and Echo, and there's just very little reason to use a Beacon + Wail kit. I mean, neither of them are that great, but I still like both. And I like the Custom Dual more. It's just fun to block people off with Squid Beacons (a tactic I like to call "beacon walling"), and either shoot them from a safe range or get them with Killer Wail. It's especially effective on Saltspray Rig. I don't know; I just love shooters, and this one is an interesting one that sticks out to me.
7. Slosher Deco
#7 is Slosher Deco, primarily because it's another one of those weapons that I love using special charge on and just grinding for Kraken. Because it's a Light Depletion weapon on top of that, I love running Saver with this thing. Slosher Deco is honestly an interesting weapon to me; I like its kit, I like the main weapon itself, and I like what I'm able to do with it. That's not to say I'm amazing with this weapon, but I do like using it for fun. However, I don't like how it never sees play just because everyone's always playing the braindead—er I mean, regular Slosher, that has the Burst Bomb combo on it, and I feel like I tend to forget that the Deco exists because of the fact. It's been ages since I've last used it... I should really use it some time soon.
6. Sloshing Machine Neo
Sloshing Machine Neo is kind of the same case with the Rapid, where I liked it from the moment I first used it, combined with the Custom Dual's case, where it intrigued and stuck out to me when I first played it in a kill challenge. I was interested in the way the weapon handled, where it wasn't like the other two types of sloshers at all. I was so happy that it made the sound a blaster makes when it directs someone, or that a charger makes when you get a fully charged shot on someone. Then it has Inkzooka, which took the cake, because I love Inkzooka as a special (when I'm using it). And overall, it was satisfying to get kills with. Like I know the Sloshing Machine Neo will pretty much never amount to anything, but it will always hold a special place in my heart.
5. Splattershot Pro
Funny thing that I actually remembered: back in July of 2015, I didn't like using the Splattershot Pro because I'd find myself running out of ink so often, because it's so inefficient (but that's probably because I spam my sub weapons like a little ***** for some reason). But now it's a favorite. I like what this thing can do a lot. I love its range, I love its kit, and I love running Ink Recovery on it; you literally shoot in from of you and you get your ink back, as long as you run at least a main and three subs. It's a 42 base damage gun, so you don't need to worry about defense hurting you unless your dealing fall off damage to your enemies, but I don't tend to worry about fall off damage if I can't even hit people.
4. .52 Gal
There's not a lot of bad I can say about 52 Gal aside from the fact that it's a Tentatek counter that can screw it over hard w/ Defense Up. But even still, 52 Gal is loads of fun to use. I especially love running Run Speed 52 with Defense. I just love running rampant (get it?) with a 2-shot mid range gun that can throw walls to defend itself and paint decently well. I used to main it in Tower Control, but I sort of dropped it after a little while. I didn't use it for very long, that's for sure. But it's a fun one, you know? It's a nice gun to use, and every time I use it in some kind of kill challenge, I'm splattin' people like there's no tomorrow (except when I'm getting wrecked, which does also happen).
3. .96 Gal Deco
For the longest time, 96 Deco was the main. It was my main gun in Ranked, and I replaced the Splattershot Jr. with it when I thought "you know, I need something with more range because chargers" or some ****, and I started using this. Now despite that it was the ultimate brain dead piece of garbage in the game for a long time, I sucked with it. It had the inaccuracy to help it paint + get shots it normally wouldn't be able to get with more accuracy, being able to trap mofos and whatnot, but I was never good enough to abuse it. I don't main it anymore, or use it nearly as much, but it's still a very fun weapon to break out for a kill challenge and just run special charge on. I'm always like "Damage Up? **** that! Even post-patch, this thing doesn't need damage!" I mean, that's because I do the Kill Challenge in Turf War, but still. Just, the next time you run 96 Deco in Turf War, run as much special charge as you can. You won't be disappointed.
2. Aerospray RG
I think that, even though it was so hated back during launch, everyone has a soft spot in some fashion for the Aerospray RG. Like especially now I don't think anyone would scroll through their list of weapons and just be like "**** that weapon!" I mean there's no reason to... But anyway, RG was my Turf War main for a long time, my Ranked main for a little bit of time, and it got me loving the MG as well as the PG when it came out. I don't main it in Turf War anymore, but I still love it. I've had so many good memories with it, including Ink Mine kills, Inkstrike kills, massively good turfing abilities to help win games, etc. I've always pretended like I was FalconXFalcon with this thing, because it IS the swag weapon of this game, and I love that about it too. Then it's a really fast shooter, and if you didn't know, I love my shooters!
Now for some honorable mentions:
1) Heavy Splatling Remix
2) Jet Squelcher
3) Octobrush Nouveau
Love all these weapons a lot, but I don't have reasons for them b/c they're honorable mentions. And my #1 favorite weapon in all of Splatoon goes to... can you guess what it is? It's...
1) Tentatek Splattershot
The Tentatek. This thing is not only my main, but it's my ol' reliable. This thing and I go pretty far back; I used it briefly before I knew it was good, used it again in Tower Control after I learned about how good it was, and after the 96 Deco got nerfed, this became my main. And at the end of last year, I decided to drop the RG as my Turf War main so I could get better with this weapon. Because I love it! And how could I not? This is arguably the best weapon in the game in my opinion (I actually think it is the best weapon), I love its ability to paint, its ability to move, its ability to kill, its ability to charge Inkzooka, the fact that it has Inkzooka, the kit in general, and so much more. I honestly feel like I couldn't really use a lot of weapons in this game because they demand a great amount of skill in one area. This thing demands skill too, but I feel like I don't have to stress it as much with this weapon, and pretty much no matter what, I can help my team just as long as I'm giving it my all and not being a scared little *****. Plus, I can deal with my worst enemies that outrange me and easily kill me thanks to Inkzooka, and Suctions help me keep people out in addition (which doesn't always work, but Suctions have more uses beyond that as well). I don't exactly like fighting against other Tentateks, especially good Tentateks, because my aim sucks so I'll usually lose the mirror, but call me a hypo because I still love using it and I'll never hate using it! Ever. I will love this weapon until the end of time, and I'm glad I've been able to do with it what I have because it's so bloody versatile.
