I guess it would depend on how many snakes you have. If you have 1-3ish then I would say go with cages. If you have 3+ then Id say go with the rack. If you have 3 I think it could go either way. You also have to take into account your future plans with snakes. If you plan to acquire more then consider the rack. Also, are you planning on being able to view them (when they are actually out of hiding) or just having them and looking at them when you open the racks.

Just my $.02

I personally have no experience with either. I love the look of the cages and want one in the future, but I dont have plans to own enough snakes to need a rack. Both choices are good ones.
