The choice really is between 2.8 and 1.4, as Zeiss doesn't really do 2.0 in a lot of focal lengths. So, compact or big? 35 and 85? The 50's are all good, the 1.7 might be even be a fraction better than the 1.4.
The 25 and the 180 are the only ones (that I have) that I found slightly disappointing. The rest is all great.
