Best HOB filter for 37L 45p tank

I know HBO filter is always gonna be the first option for beginners. But when I read reviews of this Oase Filtosmart and saw video, they way they described that filling water is all I need to prime it, and unlike other canister filters there won't be issue of pressure or air lock. I thought that its a canister filter which is like HOB in terms of ease of use.

I think it’s the same as any other external (canister) filter, just with a smaller capacity. So priming it will be the same.
