Your guess is as good as mine as to which is actually better... though just going by what I see, and (pretend to) know, the last picture is going to be the best, it has less advertised area (frontal area).
The second picture looks nice, but I'm afraid that's all... the big hole near the door just creates a "funnel" effect, which is good for making noise right next to your ear, as the outrushing air expands back into the air stream. That hole will probably
penalize you if anything, so I'd stay away from mirrors (or anything) that create another point for flow to split into more than one pattern.
There's my 1/50 of a dollar... at least
I think I'm right...
