Glass or PVC terrarium: which is better for my reptile?

Community consensus across reptile subreddits is that PVC enclosures (like the Phailozoo) hold heat and humidity far better and are lighter, which matters for tropical species, while glass tanks (most REPTI ZOO models) offer better all-around viewing but leak humidity through mesh tops and can ship with sharp or fragile panels. Arid species such as bearded dragons do fine in glass; humidity-dependent species generally favor PVC or heavily-modified glass.
