I think we can pretty much eliminate the 17-35mm these days. As good as it was during its day, both the other lenses surpass it, especially in terms of corner sharpness and chromatic aberration avoidance at extremes.
The big questions then become: do you need to use filters (get the 16-35mm), do you worry about linear distortion (get the 14-24mm), do you know how to frame extremely wide angle (get the 14-24mm), do you need faster apertures (get the 14-24mm), or do you need the most versatile focal range (get the 16-35mm). Resolve those questions and you have your answer.
