I'm getting a Sigma 12-24 II for the 5D3 in a UPS shipment in about 2 hours, so I'll try to post my first impressions tonight. I also have the 10-20 3.5 for crop so that will be a nice compare.
I'm happy with my Sigma 12-24 mk1, but I'm sure the Canon 10-22 is one of their better lenses so wouldn't be surprised to see it being the winner! The flip side is that you won't get a FF zoom lens in that range at such a price point...

Lens arrived, so far VERY impressed. Build qualty is very good, beautiful. I normally use a 135L on the 5d3 and this is a whole new real of fun. Hopefully will have some photos to post soon.
Here are a few walk about photos from today. Rather low contrast day outside. I rotated the bench slightly and cleaned it up a bit, otherwise they are right from the camera as jpegs, 5D3.
I think the lens will be a great complement to a 24-70 or some other daily use lens.
