O, under gravel filteration is the best. No drills, air pump, gravel plates, and some tubes.
run the pump above your tank, and or use hoses with water backup.
If you don't like that, go with Canister.
If you got $$$, Eheim is the best,, then Fluval FX5 is GREAT! or even a few smaller Fluval 405, 305s, Rena Filstar are decent, some people like 'em I hate them!
Stay away from Magnum filters, they are great for polishing, but the leak all over, until you get it primed. there are other off brand canister filters, but buy the best, and you won't have to buy another one. I'm a Fluval guy.
the Wet and Dry systems are great but if you are like me and hate the noise, you will not like the pumps, they are LOUD, even the best external pumps are loud. couple with having to monitor the water level every week.
Easiest thing for you is go with Canister. buy 2 Fluval FX5
