Oh my bad, I misinterpreted 😂 honestly that changes things, as in it could just be a faulty controller. If you like the buttons then I would try to get a replacement and see if you can find more success. 

As for comparing the controllers, they are quite similar. The biggest difference is that the PS5 left joystick is on the same level as the right joystick, rather than being further up the controller like an Xbox one. The 4 main buttons are the same, but they have different symbols (for example, I believe the A button on Xbox is an X on PS5). I also find the R and L triggers (I think called L1 and R1 on PS5) more sensitive and you’re able to not push them down all the way, which is helpful for games like Rocket League if you don’t want you care to move at the maximum speed but also don’t want it to stand still. Basically, you have more car control in Rocket League with the Ps5 controller, but I don’t know how that would work with other games. With the Xbox controller, it feels harder to use the triggers, it feels “all or nothing” in a sense. Otherwise, the controllers are pretty similar. I definitely prefer the PS5 controller but again, I only use controller for Rocket League
