I think the Xbox form factor is fine. I’ve used DualShock 3 and 4 a lot, also Joycons and Steam Deck, but I don’t mind the different layout. The ergonomics are good. Better than Joycons and maybe even the DualShock. I haven’t used DualSense though. The Steam Deck is superior for me, because I always use the right track pad, since it’s much better for controlling the view than a joystick is. Maybe I’ll try to get a Steam Controller sometime, but till then I am completely satisfied with KingKong 2 Pro.
