I've got an AC-50, Whisper 60, and an Eheim 2212 on my 55g.
The Whisper 60 is annoying - having to buy new filter stuff for it b/c they deteriorate after rinses, it gets clogged really fast, and has lots of overflow. I have no problem with the noise though.
The AC-50 is awesome, I've always been happy with them! I would get an AC-50, or a size up.
