I have the eheim compact 3000 and a mag 9.5 running and they're both acceptable, but the compact 3000 is absolutely silent. It makes FAR less noise than an MP10 and if it's the only thing running the sound of water going over the overflow is all you hear. I definitely recommend the Eheim over the two. No hum, nothing. I truly have to touch the return pipe sometiems to make sure it is on. The Mag isn't overbearing, but you can defniitely hear the hum and it lacks the dampening structure of the Eheim's bracket.
