I haven't had either, so I can't say which is better, but just a head's up: these filters are huge. I've seen a few people on here saying that they didn't take measurements before buying and were pretty shocked at how huge they were; they won't fit through the cabinet doors on most standard stands. Be sure to measure your cabinet doors, otherwise you might end up with a green 5 gallon bucket (eyesore) sitting next to your tank.
