Neither are beginner giants . . . Boas an OK start but these guys are just not comparable. For you its going to be get what you love and commit to keeping it. If there's a mutation you like in one vs the other, go with that. There are also Dwarf blood in both of these animals so you can get them smaller. Consider Half Dwarf burms if they are available in your state. Then there's Jampea Retics, big but not as big - looking at 11-13 ft on average for a good size female. Even consider 50% Super Dwarf crosses. These get to the 10 ft mark for girls, and 8-9 ft for boys. Have the awesome retic attitude, and can generally be found to have some of the really neat pattern mutations for a good price (SD Tiger 50% go for around 450). Here is my big boy that I posted a shot in another area tonight:
