To me, Pentax lenses are just better than Sigma or Tamron. Not that Sigma/Tamron are bad...just Pentax lenses are a little step above.
I have a Tamron 70-300mm and a Pentax DA 55-300mm. For IQ and sharpness, the Pentax wins hands-down. Plus, it keeps that sharpness and IQ through most of the zoom range, where the Tamron drops off after about 175mm or so.
