I went with the Sony 2+ years ago. And it is the only zoom lens I care about. It has been on the a55 practically all the time. I find the lens quite sharp wide open at any aperture. At f/4, I would say it is as sharp as a zoom lens gets.

SSM is super quiet, close focus (and 1:4 magnification), no zoom creep (my only Sigma HSM is 18-250 which loves to zoom on its own), no CA issues. I also love the contrast and color out of the Sony (Sigma lenses seem to favor green a bit). The only advantage to Sigma might be that it gives you about 20mm more reach... nice to have but I would rather gain at the wider side. And price.

Needless to say, DT 16-50/2.8 SSM on a55 and E 35/1.8 OSS on NEX-6 are my go to options. For extra reach, I generally have Sigma 70/2.8 and usually Sony 135/2.8 STF at hand anyway to go on either camera.

I completely second EinsteinsGhost. Also went with the 16-50 2+ years ago, and I still enjoy it almost every day. It is sharp in the center wide open at every aperture on my A57. The only negative I could think of is the distortion at 16mm (which is easily corrected in camera (JPEG) and in LR (RAW) with a lens profile).

I would never trade the f2.8 for 50-70mm zoom range. In addition, one never knows whether the Sigma will work on the new SLT models coming out especially when OSPDAF is involved.
