As long as your Porygon doesn't compose things that involve "wubs" or whatever they were called, I doubt anyone should have much of a problem with him.
Anyway, I only have experience with Flareon and Vaporeon, but... I have to recommend against the latter simply because I've never encountered one that doesn't have some sort of enormous attitude problem.
