I would say Apollo also. I have both. Apollo is different in that there is so much more you can do with him scaling wise, and morph wise. You can bulk him up or trim him down whatever you want. One of the things that I like about him is that in his "body fit" morph he actually has the "V" shape that is a reality for fit body types. If you can only get one, then Apollo...but definately get David also, he is unique also :)
