I'm new to this site, and hoped to get some questions answered. From what I've seen of some of the answers you got, I think I'll try another site. I don't think I need smarmy answers from crabby little nerds with expensive cameras

I have the Tamron lense, and although I am very happy with it, and use it all the time, I have noticed it is not quite as sharp as the Nikon lenses. That have been said, it was also a lot cheaper. I am not a highly talented professional, so most of the pictures I get with the Tamron are just fine. Would I buy it again? Yes.
