Colorful or not? Street shots

Color and black and white for street shots. Kosher or sacrilege? These are mostly streetscapes, so there may be something to say about their not being "street" but then... Take a look.

Isolation, or poor frozen bike (M5, Nokton 35 f1.4 on Kodak Plus, at f1.4, 1/125.

Corner with light and snow. Same gear as above, and almost identical EV, but on Kodak BW400CN.

Chair-Line by the Water Tower, on Michigan Avenue. Same rig, lens slightly closed (probably at f2.8) and a nice shutterspeed (like 1/250).

Why is it I remember all this? Simply because the M5 requires me to pre-meter, almost as if I had a meterless body, so that in the final adjustment I know what changes I'm making instead of turning madly the shutterspeed dial or the aperture ring.

Any preference? Let me know!
