What are your thoughts on rapid-fire weapons on Ranked?

I'm talking about stuff like the Splash-o-Matic and the N-Zap 85. Most "shooter" players in the higher ranks use either the Splattershot or slow, hard-hitting weapons like the .52 Gal. I understand that the Aerosprays are essentially useless for Ranked, but what about other rapid-fire weapons? Are they just generally bad for Ranked?

I ask because I made it up to A rank awhile back with the Forge Splattershot Pro and then I realized that I really didn't like it. While it wasn't uncommon for me to get the most splats on my team with it, it was also pretty easy for other players to splat me. I feel very comfortable with rapid-fire weapons, especially because I don't have the best aim in the world. I tried to git gud with the Splattershot in quite a few Turf matches, but it too feels much too cumbersome for my tastes. I played some SZ private matches with my friends using the Sploosh (Yeah, I just called it the Sploosh. You have a problem?) and I really liked it, but I'm not sure if I'm actually any good with it (most of the buddies I played with got the game a month ago while I've had it pretty much since launch) and I don't want to test it out on an actual Ranked match. Sorry for the wall of text.

Tl;Dr: Are rapid-fire weapons like the Splash-o-Matic bad for Ranked modes?
