I have All-glass, Perfecto, and Oceanic tanks. All work well, my oldest is about 10yrs old. I do like the appearance of the Oceanic tanks most, but they also cost more.. As for All-Glass and Perfecto, I consider them equal in quality and appearance.
The only thing I don't like about perfecto is that they are tempered all the way aroung, my friend bought a 120 perfecto and when we went to drill it it shattered in a million tiny pieces :sad:
