I outright refuse to use brushes of any kind. I find them insanely annoying to go against so I don't use them against others. I don't use the Aerospray at all simply because it never really interested me. The high rate of fire makes up for the lower damage, but the poor range just doesn't sit well with me. It seems like it's good for splatting the barrier around the Rainkmaker quickly, but not much else. Splatlings strike me as a slower, shorter ranged Charger that will often leave you in a vulnerable position, so I stay away. I rarely use Blasters, but that's probably just because I've gotten so comfortable with other weapons. I'll probably broaden my horizons later on.
I'll usually always use a Hero Replica of some sort. There's nothing wrong with showing off if you've earned your bragging rights.
My main preferences lean towards the Dualies and Splattershots. The dodge roll is extremely useful once you get the hang of it, and the Tentamissles are a great way to incorporate some long ranged combat into an otherwise up close and personal weapon. The Hero Shot Replica looks fresh, it handles well, and it's an all around well balanced weapon that's good for a wide range of situations.
I'll occasionally use a Slosher during ranked battles if I'm feeling aggressive, particularly because one direct hit from a slosher at point blank range will instantly splat a pesky foe, and it covers a lot of turf in little time. Rollers are fun to use sometimes, especially if you manage to get behind the enemy team and just mow down the lot of them before they know what hit them.
Chargers are.... An oddball for me. I really like them because I love things that require accuracy, and the Hero Charger Replica looks so fresh... But at the same time, I'm basically useless in a hectic situation where I get ambushed or something, because that's when my accuracy just goes out the window and the Charger is very bad at handling those kinds of situations. Still, the satisfying feeling you get when splatting someone from across the map is just.... I can't say fresh again, I've already used it too many times. Heck with it, IT'S SO FRESH!!
Still waiting for that Hero-Brella Replica Sheldon.....
