All of them!

Shooters. Have only briefly tried the others, my main issue with the rollers is the relative inability to use the walls.

My current fav is the Aerospace MG. It took me a while to figure out how useful the seeker is. They are awesome for getting to other parts of the map quickly (on certain maps) and great offensively as well, accounting for nearly half my kills.

I've just recently discovered I can now move in squid form without leaving a trace and it strikes me with that this could be very useful in combination with the rollers. As it is, it's pretty useful in a firefight and for sneaking up on people.

I like all of them. Each type has at least one specific weapon set that I really like.

AeroSpray MG and Splattershot.

I was doing really well with rollers but I transitioned to rapid fire gun. Can't remember which right now, though. Crazy thing is Splatoon made me fire up Titanfall for the first time in ages...

I actually swap weapons everytime, but my fave is the Sniper/Charger Family!!!!!! Especially how i LOVE the gyro controller thing. It makes it soooo much easier.

Haven't unlocked too much just yet, but I'd say Splattershot. Jr is pretty neat.
I do like switching it up with the roller(s) from time to time however

Hmm. Needs more emoticons, and more crow.

I'm a big fan of the dual squelcher. It has great range, good coverage, and I like the echo locator. People can't hide from me and I out range everything but sniper rifles. Its only a matter of time before I tag them and move on.

I only use shooters, mainly the Splattershot Pro and deco gal .52/gal .52. I do have to mention that I only play rank now.
