I guess it just really depends what you're looking for. I don't like 1-gallon tanks, I've decided. I have 2 of the 1-gal. Aquaviews and they work great. I don't use the UG filter. I also have a 5-gallon Minibow for my dwarf puffer and I love that too. I do like the "stand" thing on the Minibow, but both are great. I agree with whoever said the Aquaview looks more professional.
I really wish MiniBows were cheaper though... grrr... they are overpriced, in my opinion.
