I haven't any experience with Boaphile other than their Rhino rax(which I got rid of)Fred Allbury on the Indigo forum likes them alot.
I have some visions and while no cage is perfect I do like them.
You can cover over the vents with plastic, glass, Saran wrap etc. if you want to raise humidity.(or put in a damp hide)
The locking glass is nice because it doesn't scratch up in time like the plastic will.
Some models have a heat shroud for heating if you don't want to bother with under tank heating.
Visions are pretty sturdy.There is one crevice under the bottom glass slider. I am going to just put a bead of fish tank silicone on it to prevent crud getting in.
The black color of the Boaphiles may make a snake feel more secure(?)Cleaning out the Visions has been pretty easy.
You can't go too wrong with either. There are others too like Animal Plastics and Show case cages to check out. Good luck.
