I like that one is a square and the other has cool lore (a golden eagle sitting on a prickly pear cactus eating a rattle snake, Tenochtitlan would be founded by the Aztec wherever that was seen, which was on the top of a lake)
Simply because it has the best coat of arms ever: an eagle devouring a snake while standing on top of a cactus, based on the Aztec symbol of Tenochtitlán. It goes soo harddd
Also has the best green and red shades, period.
