Pentax vs. Sigma/Tamron Lenses

Are the Pentax brand lenses better than Sigma or Tamron? I'm talking specifically about the Pentax DA 55-300mm vs. the Sigma 70-300mm APO or Tamron 70-300mm Di LD. Also, is there that much difference between f5.6 and f5.8?

I've owned all three and I must say that I like the Pentax best. The Sigma had the least color fringing, but the first one I bought had a VERY still zoom in parts and the second was really soft. The Tamron 70-300 was super sharp, but had very bad purple fringing. Pentax is a compromise, very sharp (but maybe not as good as the Tamron), good fringing control (though not as good as the Sigma) and 'only' 1:3 macro or so.
