I would agree that your site looks more professional IMO. I don't think this means you should make your site look less professional, though. I think it might have more to do with the traffic that the two sites gets. You have higher PR but how do you compare for
traffic?
If given the choice, I'd usually go for traffic ahead of presentation. Ideally, you want both though. You're halfway there so keep plugging away at getting those links...
