Both are nice in my opinion. I personally went with tubs/plastic over glass tanks. Due to what I've read between using either one. They both have their pro's/con's, but at the end of the day it's just personal preference. And recently I've seen quality plastic/acrylic enclosures that look fairly decent. I even have my eye on this one brand of acrylic/plastic enclosures for a good price. And most likely will be sticking to them when I purchase more BP's in the future. Tanks alone look very nice, and I've seen amazing decorated ones and setups. But I still like the whole tub/plastics better, just my opinion.
