Taking a close look at them all as pictured here, I picked Barber. The huge honking mintmark was a really big factor, but the other lettering is jsut crisp and clean. Mercury has a nice reverse design, but it is a bit busy. The barber also seems busy but the level of details isn't from different elements, just that kind of detailing in the wreath. Also it isn't crowded like modern coins seem to be thinking you have to fill all available real estate space with something. Overall good clean design, and the obverse has my preference of Greek over Roman features. (Yes know the Morgan's model wasn't a roman girl.)
