I have them both and I love both of em. They are awesome. My oscar recognizes me, lets me pet him (occasionaly) and it is great fun to see how excited he gets about food, though he has jumped clean out of the tank several times... He has more personality towards me than my Jack Dempsey, but I could watch my Jack for hours, I love how he changes colors when I come to the tank and how he interacts with the other tankmates. He is the smallest by far, but doesn't let himself get to bullied. They are more beautiful than oscars IMO, so all in all they are both awesome fish!
