For me, anything that I could be playing, I’d rather be playing on my PC than my PS4. The performance is significantly better (even on a Pro) and I can play with a more accurate controller. For the times I want to play on my TV, I can grab a controller and play via my Steam Link.
The Switch changes that with it’s portability. There are times I’m not around my desk or my couch and want to play a game. I’ve only had my Switch for a few days but I’ve already used it more than the PS4 the entire time I’ve had it for that reason.
