Also, controller > KBM in rocket league

Nah, OP definitely thinks Keyboard users would destroy controller users in Elden Ring PvP (they absolutely would not lol)

In FPSes, the aim assist is too overpowered in a ton of games because if they had to actually aim they'd never go positive. The only FPS players on controller I respect are Rainbow Six Siege console players. I even dare to say that a Silver R6S console player is better at aiming than a Crimson (highest rank) Call of Duty console player.

Some people just don't realize how carried they are. No one should get an aimbot for free for choosing to play on a PS5.

There's bad on both sides no doubt, but my experience has been 8/10 times the console player is the one talking about my mother or getting all excited to say the n word behind the anonymity of the internet. Could be just that there is a larger player base using consoles. Anyway, the toxicity you're referring to is a bias that has been built from individual experiences. Try a few rounds of vanilla Arma Reforger, there's a noticeable difference between thr console and PC players in that setting.

XDefiant felt dirty with crossplay on.

A buddy of mine and I had problems playing against console players, the aim assist felt way too strong and I think there was mention of it somewhere.

So we turned crossplay off and we had a much better time instead of getting stomped on.

The aim assist is the only way my teammate Jimmy No-Thumbs can possibly get any kills. He's still going 4-32, but he's trying his best.
