If people didn't think Seth was perfect I don't think this thread would have been born.
But really, I just don't see Seth as a person who has ambitins to get away from the place. I mean Leah and Sam, sure, probably Jake, too. But Seth is just aways content with life, I can't imagine him wanting t go somewhere else out of ambition, plus, La Push is FULL of scenery! I can barely remember the last time I saw a green forest!
