I didn't like the aquamaxx (great build quality and thick acryclic)... and I love MD but I didn't like the outlets on top that aren't really adjustable, the thumbscrew under the barb that's hard to screw on and off, and the mere size of the tubing you have to use for it.
The cadlights, although it has a separate pump is under the body and doesn't take any more space, basically filled it up and plugged it in and done . The cone shape helps to tumble the pellets very well and at a slower rate where they kinda fold from one side to the other... I think its really preference at that point.
