I currently have the Zeiss 35 f2, 100L macro, and 85 f1.8. I've also owned and sold the 50 f1.4 and 1.8 and the 24 f2.8. The macro is the most fun. The Zeiss is the sharpest wide open (scary sharp even at f2) but hardest to use because it is MF only. And the 85 is the best value. If I had to pick just one, based on my experience only, I'd choose the 100L macro.
