I do like glass, I like PVCx too. I have 6 of each. Add a few other types too here and there (custom using specialized materials). I can't say one is better they are about the same to me. Just different. Glass heats easier using less power to heat through. They also hold heat longer (mass, or density) so the heat is on less. This reduces the power bill. They also resist spikes caused by on off stats (not that I use any) but many do. Glass is way way easier to clean. PVCx holds heat better but is equally harder to heat through. It is ok to clean if seals at the cuts but can stain and sags by times. (you can very quickly add a bit of insulation to the glass tank to hold in some heat) They are stupidly heavy and scary to bang around, this is the big downside to me. I think PVCx is a better look and stacks better and can be modified easily, drilling glass is not easy! 50/50. I think that especially for smaller snakes a small side turned tank is quite a win. Small tanks are very cheap and side turned solves all the open top issues. Better than a tub anyday, and as good as a pvcx enclosure in the 15-30 gal size for sure.

I am in Canada, every pvcx enclosure must be shipped I bought a vision (roto mould) ages ago and the shipping and duty doubled the price. The canadian suppliers are more expensive but there is no import costs so it works out, but the shipping is the killer. Tanks I can pick up off the shelf, even larger tanks are cheaper. (55g bigger gets dumb but a 55 side turned is a big enclosure)

I don't think it matters what the enclosure is the keeper makes it the difference, the rest is just preference. I have enough experience that glass tanks pose no issues at all, PVCx, rotos, tubs, and metals too it does matter I have set up all of them and had no massive issues they are just different.

nicoleebriannee I am not a huge fan of racks. I own one and use it but i don't love it. I because of my home heating the room is not very practical and the most difficult heating I have encountered is the rack in a cool room. Ultra pain in the butt, they save space but that is about it. If you have an open top tub rack they take as long to clean as anything else (per drawer) and if you are a big person (like me 6'4" 260lbs) it is a lot of bashed elbows trying to reach the back. I too prefer a stack of enclosures.I think any enclosure type offers a versatility of heating that you can't get with a rack.
