I must say that we have never tried one of the "cartridge bucket", so I can only say here about the product Diaper Champ and not make comparisons.
The bucket completes relatively odor-tight, in fact - he is with us in the bathroom and is currently emptied once per week on average. From the bucket or the content no smell comes from.
The insertion of new and removing full trash bags just goes out of hand and all the mechanisms for opening and closing function properly.
One should only pay attention to use something more stable garbage bags, because the bucket up a tick becomes narrower, creating a full garbage bag when removing u. U. could take damage. (Is with us but never happened.)
