Fair enough. I guess it comes down to what is more important to you...Aesthetics or performance. For me, I want the healthiest acros possible and for that, the gyres win hands down in terms of providing the best flow. Also, price is not to be ignored. 2 MP60s will cost you $1400. 2 XF350 Gyres with a controller will cost you around $500. After having owned both, I can tell you the $500 gyres are the clear winners. I personally think they are less of an eyesore than a giant mp60 and they are easier to clean around. The new controllers have a couple of preprogrammed flow cycles included that I think are perfect and I see no need to change constantly, so the controllability thing is also not a problem for me. To each his/her own though.
