Hob filter or internal filter?

The title says it all. Im currently using a hob filter on my 20 gallon but the currents too strong. So I thought about replacing it with an internal filter. Which is better?

I don’t like either. I like canister filters. Have you considered them ?

In any case, I think the best filter is the one that can house the most biological media while doing a good job with mechanical. I think an HOB would be better in that context.

You can slow down the current by adding a sponge filter, or dispersing the waterfall using a botlle or other things. IMO, internal filters are great but they look ugly and take up space
