I've got quite a few, so let's see here...
For Shooters, I like the Aerospray RG, the .52 Gal Deco and the N-Zap '89. The Aerospray RG has really fast fire, Ink Mines for when I feel like dropping a mine on something and Inkstrikes to drop on enemies or Splat Zones/Towers; it's pretty weak, but getting close mitigates that weakness. The .52 Gal Deco has fairly good power and range, Seekers to throw at enemies from a distance and travel behind, and Inkstrikes to drop on enemies/Splat Zones/Towers; its speed leaves something to be desired, but it's alright otherwise. The N-Zap '89 has a fast fire rate, decent range, Sprinklers to cover areas and charge for Inkstrikes, and Inkstrikes for Inkstrike things; it's kinda weak, and the lack of spread hurts at times, but this is still a good weapon. I could put the Tentatek Splattershot here, but I prefer the Splat Roller.
For Chargers, I'm okay with the E-Liter 3K Scope and the Splat Charger. The E-Liter Scope has insane reach and good power (especially after a Damage Up or two), Burst Bombs for close combat, and Echolocator for a free refill and to spot enemies for easier sniping; it doesn't charge quickly, and my aim sucks most of the time, but it's the Charger I'm most comfortable with. The Splat Charger charges fairly quickly, does pretty good damage (after a Damage Up or two), has Splat Bombs for rolling on the ground for close combat or throwing over walls, and Bomb Rush to cover sizable areas in high-damage inksplosions; I'm still not good at aiming Chargers, and the lack of Burst Bombs isn't great, but it's alright.
For Rollers, I like the Splat Roller and Gold Dynamo Roller. The Splat Roller is the Roller answer to the Tentatek Splattershot; it has decent range and power (and with a Damage Up or two, the edge can splat fairly reliably too), you can roll to create a wide inkroad for your teammates, Suction Bombs are good for making enemies move (good against Chargers), and Killer Wail is nice for making enemies move from across the stage as well (especially in Ranked, where I can aim it toward the Splat Zone or a nearby sniper perch or the Tower and generally affect someone); its range leaves something to be desired, and it's not that quick, but it's very well-balanced, able to take on most situations. The Gold Dynamo Roller stands in contrast to other Rollers; it rolls slowly, swings slowly and is very ink-inefficient, but in exchange its swings are HUGE (and with a Damage Up or two, the whole thing splats reliably), it has Splat Bombs to toss at Chargers or other longer-ranged foes, and it has Inkstrike to do Inkstrike things; overall, the opposite of other Rollers, and a pretty good weapon.
For Brushes, the Octobrush is the only choice. It's fast, its swings are respectably strong (3-shot splat), it has decent range (especially on the sides, seriously I get so many splats on people just off to the sides of me), it has Squid Beakons to place so your team can follow you (or so you can return to them if you get splatted. Which I do. Often), and it has the Kraken to release when you're under attack to get away or when you're about to ambush foes to do one-hit-splats; its range is still fairly short, but it's a great weapon, at least I think so.
For Splatlings, the Heavy Splatling is awesome. It requires a bit of wind-up to be most effective, sure, and its damage per hit is kinda low, yeah, but its fire rate is absurd given its long range, it can spray for quite a while to cover sizable areas fairly quickly in a single burst, it has Splash Walls so you can wind up in peace before unleashing the deluge, and it has Inkstrike, which is always welcome. Overall, a great weapon, and a personal favorite.
I'm not good with Blasters at all, and I don't feel good enough with the Slosher to say I'm alright with it yet.
That's all for now, maybe there'll be more in the future (looking forward to future Splatlings in particular).
