Ive never bothered to use anything other than fluval.
I have used at least 5 different ones over my lifetime...
I have never had one break down on me.. always sold them with the tank.
I never heard a single noise.. In fact I can open up the cabinet under the aquarium and stick my head in and still not hear a noise. If I touch the top near the impeller I can feel a slight vibration... other than that and the fact that water is flowing from the exit tube, You couldnt tell the fluvals are on at all.
Note: This is just MY experience. You dont have to agree with it... but no need to flame me for having good luck with fluvals
