Ergonomics wise, but can you have those where it can charge it at the same time, do you want to wear out your $1000 cell phone battery, and I doubt any of those controllers work as nicely as a ps5 controller. Plus the screen is smaller and you won’t have a lag free audio jack.
Plus the good ones that you attach to phones are already $100. At that point I’d rather spend an extra $100 to have something better, bigger, and dedicated?
