Hang on are much easier to do maintinence on.  If you have a problem with doing regular maintinence, stick with the Hang on. 
 
I have a couple of Fluvals, and they work good.  However, they are a real pain in the backside (**insert much stronger word here, mabey even 2 or 3**) to get primed.  I have never used the other 2 filters, but if there is one that is easier to prime, I would say go for that one.
