AquaClear are better for mechanical filtration. They have a higher flow rate and the motors never die.
That being said, I prefer Marineland filters because they offer superior biological filtration.
My recommendation is to Cut the blue mesh open and remove the charcoal out of the media carts they come with and then once a month, float the biowheels in your aquarium and spray the entire filter in your sink. Spray off the cartridges.
Spraying the hell out of the motor drop with hot water will improve your flow and you won't have start up problems or a slow turning biowheel anymore.
I was thinking I'd try to go sponge in the bottom, biomedia in the middle and another sponge on top. What biomedia is best? I've heard people ditch what comes with the filter and go with other options.
