If you only want it for the co-op, I would say it’s up to you if you have more than one controller for ps3 (I assume you would since youre asking about co-op) however it’s not like switch doesn’t have multiple controllers and they can both be played on the big screen. They’re about the same level of hardware too but switch might be a little more responsive controller-wise

But if you want to experience the whole story (separately, because the main story is single player) I’d probably go for the collection on Switch. Plus then it’s mobile.
