I'm in kind of the same dilemma- I'm considering either the Tokina 16-28, Nikkor 14-24mm or 16-35mm.
Besides cost, another bad thing about the 14-24mm is that you can't put a CP filter on. Yeah, I know, sometimes that can make a sky look unevenly blue. But a lot of scenes which deserve UWA glass (large body of water/other shiny background or country green pastoral scene) benefit from being polarized.
You may also want to consider a used 17-35mm. New, it sells for $1,700+. But if it has a "squeak" when it focuses after sitting unused for a while, then the owner will likely think it's about to imminently die and want to part with it for $900-ish. Sort of the same syndrome as "That camera body has over _ _k shutter actuations- it could explode at any moment!" But when I had one, I felt like not having the Nano coating of the G series made enough of a difference to me that I sold mine.
The Nikon 16-35mm might fit what you're looking for- but some people are bothered by its supposed tendency to curve architecture. Never owned one, that's just what I read.
