The Sigma I had for a while, as well as the D7100. The lens itself I find outstanding and I only sold it because I wanted to focus on FF. I found some samples on my gallery.
For me the main difficulty, was to get a proper reference to focus on. The frames of the AF points in the finder were sometimes just showing too much to know where the focus would be, especially wide open. And if your don't need "the fastest AF wideangle zoom", you might be better off with a less faster lens? The weighta ns size is also something to consider. Today I have mixed feelings about the combination - not the lens itself, but once I found a very interesting article on DPReview which used the lens together with an EOS 70D (I think, it was a new body with combined phase and contrast AF).
To me it appeared the Canon got more sharp shots than I sometimes had with it although I adjusted AF. Anyway, ever since I would not try Nikon + APS-C + fast aperture + wideangle, except if I could always use LiveView. For mroe details: http://www.dpreview.com/reviews/canon-eos-70d/12, scroll down to the heading " With 3rd-party lenses: Sigma 18-35mm F1.8 DC HSM"
If you're thinking to go FF, forget about the Sigma 18-35, but maybe consider a 10-20/3.5 from Sigma or 10-24 from Nikon (I found that also very nice). The others you listed are already FF.
Do you live somewhere where you can rent a lens? That might be a good idea to find out what you like most.
