Hmm... good question. I feel like I could toss out a few names but a few minutes later I will remember someone else. I guess, for now, Walkman, Daboss, and Black status (how is he so good with the splattershot jr? I need to play with him more to see if he just got lucky games or if he's really that good). There are also other people who are really close to them but not quite there; probably violet (I wish I could see how well he would do if he didn't lagg, I can't tell if it's helping him or not. I don't think it is but who knows), robotguy, you, Guysloth, and blue on a good day.
For people who I feel are good at turf wars, I'd say Azure, Zero (brush players are too sneaky, they force me to play defensive otherwise we lose our base), and Tingly.
There are a few players that I want to play more with but they are either practicing new weapons or they don't play that often. This list feels incomplete but that's probably because I've been playing less Splatoon recently.
I don't know if I would say I'm better than you. In terms of killing people, I'd say we're about even. Mobility wise you would beat me. I would also say I'm not really a team player either since I use my team as bait (I paint the ground close to them which makes them advance into enemy territory and kill whoever pops out). Overall I'd consider you better than me.
