Not that naive - Acrylic bongs will stain over time, plus they get scratched real easily. Plastic is much more porous than glass, so even when freshly cleaned, most acrylic bongs have that bongstank...

The main "problem" IMHO, with acrylic/plastic bongs (and some glass) are the ones that use a rubber h-grommet to seal the stem to the bong, or an o-ring to seal the bowl to the downstem - this is where 99% of them leak, since the grommet is not offset to allow for the proper angle of the downstem, and the O-ring was not designed for sealing in this configuration (gravity seating against a conical flare). The rubber parts absorb stanky bongwater. They can and will break down over time, turning into some form of mush or paste. What heat range is that grommet good for - will it break down in bongwater? Unless you are using Viton (doubtful), then you don't really know

A good glass on glass bong will last you forever if you don't break it, and will always seal as good as the day you bought it, if cleaned. The glass seals can be re-used indefinitely. Glass cleans easier than metal or plastic
