What PSP compilation would you recommend?

[kupomogli]

While I'm not a fan of digital content, I'm thinking of purchasing one, or maybe two of the compilations currently available for the PSP digitally to play on the PS Vita when I happen to be out and decide to not want to play the Vita game currently in the system. There are other compilations, but I've only listed these because I think they're the best value and have the best games.
