I don't know much about Noel and I think it's far too early to make a call on a character until the video game is released and we find out more regarding his story and personality.

Also, Tidus is awful and saying that Noel makes Tidus look good is a terrible thing to say. Even if Noel turns out to be a stinking turd, that doesn't make another stinking turd look good. It just makes them both look like stinking turds.
