All filters do the same thing (unless specialized)
A HOB, is no better or worse than canister, or better or worse than a sump.
Sure....one may hold more bio-media than another, or hold more or less mechaincal media, or provide more linear flow, but in the end they all do the same thing, so its really about what you are comfortable with, and which one prompts the you the aquarist and your time constraints, to do the most and best maintenance practices for your particular tank.
Sufficient bio media is related to your specific fish load (the food that beneficial bacteria use), not volume of that media (unless of course you provide too little).
You do not ever have more biofiltration than the ammonia the population of fish put out, just because you have more square ft of media.
If you have 2 or 3 HOBs on a tank and you find you will rinse the mechanical media of 1 filter, every other day or so, then this type filter may be better for you, better than a more highly rated can, that gets only monthly maintenance.
If you find taking a filter off line, and apart to clean, a complicated or tedious task, that type might not be right for you.
If you find fluid dynamics and plumbing a pain, a sump may not be for you.
Because my focus was on breeding, my tanks were often heavily stocked, so I would often line the entire back of the tanks with 4 or 5 HOBs, and give one a daily rinse.
In the past I always had 20 or so tanks running at the same tome, and I found I could filter 5 of those tanks with a single sump, and single pump, so using a sump was a no brainer for me.
These days I prefer my nitrate load to be 5ppm or less, so I prefer to use sumps, and I can do a daily rinse of grunge of the mechanical media without turning off my pumps, or disturbing the functions of the main tank at all. I like my tanks to have a minimum of 1000 GPH flow, and lots of turbulence, so a sump easily provides this and more for my situation.
