The pro pad wipes the floor with PS4 and XB1 pads. Not that they are bad - I have and like both - but the pro pad is the best I've ever used and noticeably better. The sticks are freakishly good! Arguably not essential if you have other options, but if you want to play the best Nintendo games in the best way, go for it. I wouldn't wanted to have played Breath of the Wild and Odyssey with anything else. What I really want is to play other consoles with the pro pad ..
I'm surprised there's so much love for the Pro Pad, I don't dislike it but I don't like it either, it was when I bought it the best option other than using the default controllers. I would take the DS4 and Xbox Elite controller over it any day.
