HELP! Which would you choose?

[Fischer's Angel]

Now I'm confused!
I need to choose a skimmer for my future 55 gal. mixed fish/invert. It will have a 30 gal. sump w/DSB. I would like the skimmer to either be in sump or if HOB then it must be capable of being hung on the sump.
I've had people say Aqua C is best choice,and others say Aqua C is junk, go with Euroreef Rs80. I can't afford two skimmers so help !
I'll go with the majority choice - Aqua C or Euroreef Rs80? Which would you choose? I want efficient,quiet and no microbubbles in my tank!
