I actually went the other way when I set up my tank. I had an in corner air driven filter and went to an HOB filter and am much happier. The bubbles from the sponge filter was just too loud for me and made my room sound like a fish store. Also there weren't many options for smaller sponge filters which take up a non-insignificant amount of space in my aquarium. Also the bubbles from the filter would spray water all over my aquarium top and since my water is hard would cause deposits everywhere.
