Correction: the Sigma tops out at 24mm. It's a noticeable difference.
I would use an xx-35mm mostly as the only wideangle, the next lens being the 70-200, the 100-400, or at least the 45mm. Though I'm using the 24-85 sometimes, too. Point being, 24mm vs. 35mm at the long end is a pretty big deal. The ability to mount standard 77mm filters (though heaven only knows how big the vignetting is...) is as well.
