I'm really liking Ness in P:M. He's the most powerful he's been in any Smash game, and I think he's got a lot of potential that has not been maximized yet. But you can say that for any character really, it takes time for players to really start optimizing their play with their character. I was playing friendlies with a friend one day (who is really good, much better than I) who mains Mewtwo and the only game I managed to put up against him was with my Ness. I'll post it later in the video...
