What made you decide to go with a rack system?

I have 3 snakes, and I don't have any trouble with heat or humidity based on my setups, but space wise I feel that a rack would be beneficial.
I do love seeing my reptiles and they have some very aesthetically pleasing viv set ups, but I recently came across the C-Serpents V-70 rack (3 tub) which would be perfect... plus I will only need one thermostat which would be a plus.
I am really on the fence and not sure which way to go at this point, just looking for some advice/pointers
