Depends on how many you plan to get, I have a boaphile cage for my bp and plan to add a couple more but my snakes are all pets and limited in number, I'm never going to have 20 snakes around and like the cages to look nice and easy to see into. Since they will be here for 20+ years they might as well be in style.
Tubs are great if you have quite a few snakes, easy to deal with, less space taken up, but not as attractive to the eye. Boaphiles turnaround is quite slow so keep that in mind. I wanted a black cage and the possibility of other colors down the line so I choose them, plus they are in the same state as me.
