I don't care for those things, if a girl has beauty on the inside, that's all that matters. Ha ha, I'm a leg man.
Seriously, both matter so little to me I wouldn't even know what to pick. As long as a girl isn't fat (and when I say fat, I mean FAT), has a pretty face, and has nice hair, that's all I really care about. But if you're twisting my arm...I'd have to go with the tatas.
