Haven't used most of those mentioned, but the Canon 28/2.8, and Collapsible Cron work well for me in b/w, good sharpness, at least in the centers wide open. The hexanon ltm 50/2.4 collapsible is sharp all over, but without a hood and shooting towards but not into the sun can give an old Elmar (50/3.5 ish) looking flare.
The 35 pre asph lux works well in b/w, but the before f2, can give the circular signature and veiling flare it's known for when shooting into the lights. When not shooting into the lights, it's just a good fast lens, with sharpness in the center and low to medium contrast.
