B is my favorite.
The pavement in A, asphalt and concrete, is more dramatically lit than it is in B. Whereas the gradient of light and color across the facade is more complex in B. This results in my reading of the building in A as a fairly flat object pierced by the open bay and my reading of the building in B as a three dimensional object in competing and balanced lights on a rather flattened field.
Yesterday, halfway through my 5 o'clock drink, I almost went out to photograph the near-by well lit tennis and basketball courts from a prospect I had studied. I stayed home; telling Stacy that I would just be imitating you. Also I would have needed to hurry because I prefer the earlier balance of light seen in B.
