Rarely do I say this, but I agree with UN?. Nava is doing great, and I definitely think he has it in him to be an everyday player in the major leagues, but he's nowhere near the level of Hamilton. Yes, he's doing better than Hamilton this season, but it's not even May yet. Middlebrooks looked like the next Barry Bonds for a couple days at the beginning of the season, and look at him now. There's no guarantee that won't happen to Nava at some point in the next month or so. (In fact, I don't think it will, but you never know). The only way I would concede that Nava is better than Hamilton is if he can sustain this level of play over the rest of this season while Hamilton doesn't.
For the record, also, I never wanted Hamilton anyways.
