I miself love playing the actual console, since emulating ive seen a lot of bugs and while people say that having the console takes a lot of space specifically the games (specially for old consoles), but on my case, I use an everdrive, its not emulating but more like a reprogramable cardtrige, defunetly gives you the best experience, and for the ps vita, you cannot replace it with anything since its perfect as it was made, and also because mobile emulating is pretty bad
