It's a bit of a trope but PC gamers do seem more serious in general. I observe some pretty stark differences between console and PC players in Battlefield 6. It tells you in the scoreboard what platform each player is on, so it's really easy to start seeing the patterns.

The number one thing I've noticed is that the PC players will almost always try to wait for passengers to hop in vehicles they grab. They also tend to be orders of magnitude more capable with said vehicles in terms of coordinating with engineers for repairs and focusing on objectives.

I do think the control scheme is too constraining for Xbox and PlayStation users. There's just too much going on. Different modalities don't map so well. I wouldn't be able to think straight if I had to use my Xbox controller to do cqb shotgun battle and then transition in and out of vehicular combat roles rapidly. It feels to me like trying to run a WoW raid with a 4 hotkeys. The auto-aim handicap sounds like a nice bonus but it's just not worth the frustration everywhere else.
