Mine's a combination of the two. I've got built internal filters and bought filters with 'bumped up' bio filtering. Personal preference is HOB's for the versatility and cleaning (you can clean some and leave others untouched not disturbing water chemistry).
Kinda paranoid about overflows, sumps and floor flooding, but that's just me. I remember looking at Utube and there were 'wars' over the 'best' filtration. But it's really about efficiency, not brand names. Numerical ratings are misleading for certain and don't take into account the type of fish you have and their bio waste. I was more than a bit surprised at some of the inflated canister ratings, even the top brands.
