I have a RTB and am sooo happy with her! I will always have one. I think they are amazing animals. However, I have not owned a BRB, but I want one! That will be the next species I delve into I think. So I really can't pick one over the other - except to say I'll always have a RTB even if I find I like the BRBs just as well! Maybe I'll always have to have both! :D
BTW, did you all notice that the poll is EXACTLY split 50/50 at this precise moment? LoL.....
