I chose the 9-18 over the 7-14 ...

We hear over and over and over that 7mm is much wider than 9mm-- a true statement. But also, the 7-14 has no 18mm focal length, and personally, I find the range of the 9-18 (18-36mm in FF terms) much more useful as 18mm is much "longer" than 14mm.

I've owned and used both but only have the 9-18 now-- a real gem IMO.
