When you say hang on back filter, are you talking about one of these? I would never put one of these on a reef tank for several reasons. Also, what size tank are we talking?
HOBs, canister, and sumps are all the exact same thing - places to stick stuff, move water around it, and add water volume.
You'll need to supplement water movement anyway so just use whatever.
HOB max extra water/storage is about 1g (aquaclear 110), canisters get bigger (3g for a bigish one?), sumps go as big as you want.

It's pretty tough to get a skimmer and heater in a HOB, all-in-ones are a little better.
Depends on your tank volume? If your able to keep it super stable , you probably don’t need a high fancy filtration system , many many people have kept successful reef aquariums with minimal filtration mostly softies and LPS
People who keep successful, simple, set ups
