Hmm, really hard to tell with these tests, cuz I can tell the mic position isn't identical (BR is A LOT closer to the dustcap than BL, for example). You have a straight cab, right? I'm surprised there's this much of a difference between the top and bottom, though once again that could be due to position.
BUUUUUUT, if I had to choose (and I don't like to, because I doubt the speaker has much to do with it), I would say I like TL the most, cuz it doesn't have as much fizz as TR or BR, but isn't as dark/cloudy as BL.
