Honestly I play both. I prefer the feeling of pc more, but it gets old without friends. The game is a lot more worthwhile when you can play it with your friends unless you're overly competitive and only care about ranking up. Which is also way easier on ps4. So that's my vote
Personally I'd say PS4! Or maybe both in the future? It's more fun playing with friends so I say start out on PS4, you'll probably even make more friends on it too. I've made a few cool people by playing on PS4
