"A" is the "cleanest design" with the least lines.
This is appealing from a design standpoint and will give off the impression of being "higher-end".
I think it is better if someone asks me, "hey, who made that"?
That's more likely going to lead to a conversation (fun to let someone know about our stuff) and someone actually remembering the brand.
Otherwise, someone might try to read and remember the brand but not ask...and not remember.
