I'm considering getting a third party UWA lens for my 7D. Which lens do you think is better? price-wise both are about the same, how about sharpness, color, build-quality and focusing?

Use to own the canon 10-22mm and tested my friends copy of the sigma 10-20 f4-5.6. The canon is a tad sharper at the corners but neglible if you are not a pixel peeper.
Prior to purchasing the canon, i had deliberated on the toki 11-16. After much consideration given the fact that I use the uwa landscape where usually is shot between f8-11, sometimes 16, the constant aperture didn't really appeal to me. Thus settled for the canon instead.
I have not tested the toki under the same conditions thus can't comment. In terms of build, I would favor the sigma. Focusing speed pretty much the same. The toki seems to have a good following here though.
Sigma 10-20mm f/3.5 costs about $1,100 street price brand new.
Tokina AT-X 116 PRO DX costs about $910 street price brand new.
Constant Aperture
Sigma 10-20mm stands at f/3.5. Tokina's at f/2.8.
Focal length multiplier
The range on the Sigma is wider than Tokina (10-20mm vs 11-16mm). Do note that on ultra-wide angle zoom lenses, a difference of 1mm is alot when translated to cropped sensor.
Summary
In short, if you are willing to sacrifice wider zooms, the Tokina gives you bang for the buck, and at f/2.8, you can use it for indoor photography where flash is disallowed.
I personally bought a Sigma because I prefer the wider focal length multiplier.
