Thanks for the samples in this topic, I've been teetering on the edge of getting a new copy, and now I'm really compelled to do so.
Teetering done, lens ordered! Yee-ha! 
I think you'll be pleased with it's performance, optically it is good; just doesn't have a 'snob' value.
Below is our latest picture shot on the 35mm f2 and below that a comparison we shot on the 35mm L f1.4 of the chapel at Marlborough College ( where the Duchess of Cambridge - nee Kate Middleton - was at school).
At f8 to 11 there is no difference.
It
is a great little lens

To be honest I expect to use it most at about f/2.8 to f/5.6 and not to stop it down all that much beyond about f/9. Its main uses will be travel, street, low light and as a contingency lens that can always find a place in my bag (like the 50 mm f/1.8 Mk I). Yes, (small) size does matter!!!
