I recently switched both my tanks to canisters.... I couldn't come up with a compelling reason to favor one over another brand.
Eventually I more or less threw a dart

... bought Fluval 405 and 205 simply because they were priced right and in stock
Both are running fine, easy to set up, not silent but WAY quieter than the
HOB's were!!
And next time I have most of the water out, I'll be able to push the tanks back 3 inches closer to the wall ! They're in living room and family room, so a clean look matters a little on these tanks.
