My choice is Fluval AND a multi layer(plastic,ceramic,charcoal) filter these are much better at keeping your tank healthy and clean, the most important thing in your tank is BACTERIA (i feel like MR bacteria of the advert ) Bacteria eat fish waste and food waste etc, bacteria live in the sponge and ceramic of the above filters. the more bacteria the healthier your tank.
Bacteria will live in gravel but no where near as well as in sponge etc. also the undergravel system tends to pull the food deep down into the gravel where the fish cant get.. then it rots and makes the water cloudy and your fish i'll
I use sand on the bottom of my tanks too......... stops almost any uneaten food getting trapped...
