I keep both and could'nt say I like one better than the other. I do think the GT looks better when bigger, especialy a male with a nice hump, IMO. Both fish look great together. Gotta love a nice EBJD though.
unless u get a ebjd i would def get a GT. I like their attitude better and i personally like their color better...when they get that bold orangish red stripe on their top fin it is amazing.
