I've watched Luck practice at Stanford before a game as well as Alex Smith w/ the 49ers before a game and I can say that Andrew Luck is WAY more talented than Alex Smith. In practice, Alex Smith was throwing behind, too high, all over the place. Andrew Luck on the other hand was solid. His throws were right between the receivers' numbers every single time. I was impressed seeing it in person. Luck is also a bigger body and though he's "unproven" I think he's miles ahead of Alex Smith.
In response to Post #2, I would absolutely trade Luck for Patrick Willis, because the QB is THE most important position in the game and makes or breaks a franchise! Just look at the Colts.
All signs point to Luck being successful in the NFL, and with good coaching and especially HARBAUGH, it'd require a massive turn of events for Luck to ever, well...suck.
