I don't own one but you will read on here that alot of people love the ac filter. I do own a fluval c4 and it works great
I don't recommend Fluval C series. Nice design, but 3 units I have are temperemental with impeller jam/stop working. I vote for the AC series of filters.
I used to mostly use . Now the aqueons 55/75 are my go to filter. It has lots of space and I like how the compartments are set up and the extra bio filtration added by the blue dividers and the blue strip up front.
Sun sun has a HOB filter with a built in UV. I never used it but it is something which might intrest you.

I think the aqueon 55/75 is the best. The aqua clears are nice too tho. No experience with the fluvals but the emperors make a lot of noise and I've had a lot of impeller issues with mine.
I'm sure people have had great results with various brands of HOB filters. I'm more of a canister or sump guy but, if and when I need a HOB power filter, Aqua Clear is the only one I would choose. I have ran some for a great many of years with no complaint.
Aquaclear and Fluval have been good values and worked well for me. If a good airpump and sponge type filters are an option, i prefer that on multiple smaller tank setups over the long term. Then again, it is hard to turn down good sales on the ACs and Fluvals when i see them.
