Tamron or Sigma 70-300?

If you were going to buy a 70-300 lens for the K10d today, which would you get. Tamron or Sigma?

And why would you make the choice. Which is the better lens? Thanks.

Being that I own both of those lenses, I can tell you with out a doubt that the sigma lens is a better lens ''imo'' why? Because it auto focuses faster and it is much sharper where the Tamron is soft...Price wise, I believe they are very close..so price should not be a factor...Sigma all the way..
