Does the Switch cover PSP and PS1 emulation? That's pretty much the only other reason to get the Vita if it's exclusive don't interest you.

>PS3 has some PS1 and PS2 incompatibilities
There's also the fact that emulation on the PS3 (Even PS1 emulation) has frame rate lag, which makes half the games unplayable, and the rest a chore after half an hour.
Honestly, OP, just get a PS2 if you want to play PS2 games. And, you're going to have to mod it anyway (Unless you buy an imported model) since a large chunk of the good games are Japanese. Or, you could buy a PS4 and inject PS2 games, but I haven't heard anything about the overall comparability of it.
