To me, the main difference between a RTB and a Burm is their size. All-in-all, I think this should be your #1 consideration.
> Do you have room for at least an 8ft x 3ft x 2ft cage?
> Do you have the money to buy such a large cage or are you able to build one?
> Can you physically handle a 16ft-plus snake?
> Can you afford to feed such a large snake?
I feel that burms are gentler, more docile, in general. However, most boas, if handled often & properly, can be just as nice.
The odds are, regardless of what species you decide to keep, their temperament will ultimately fall back on you, the way you handle & care for it.
For most people, though, a boa is the better choice, mostly due to the fact that they don't get huge like a burm does.
I've got an 8ft male & a 10ft female burm. The female is sitting on about 20 eggs with just over a month to go before they hatch. Both the male & female are het for albino. I wouldn't take anything for either one of my burms. Love 'em to death!
Best wishes!
