I have both and I like the 35 f2 much more than the 35 1.4 and I'm using it more than the 23mm 1.4, recently. I'm contemplating checking out the 16mm 1.4 but i can't seem to commit and the current price just yet. I tried it at B&H and though it was great just the size kind of put me off but it was smaller than what i thought it was going to be.
