Not to long ago I chose between those two lens, not based on $. Strictly what I would shoot more. I felt the 24-70mm crept to close to my next lens, 70-200 2.8. The 17-55 went as wide as I'd need with out fish eye/barrel rolling to much on the shot. For me, a 10-22 had limiteduse for what i shoot, the 70-200 had huge use, so I fiddled in the middle with a 17-55.


I feel certain either lens will resale well if I jump to FF, so the loss isn't worth staring at.
