I would also pick parts based on cosmetics, provided they were a functional equivalent. I lucked out because I liked the look of the Mt800 better but that's just my opinion. FWIW I looked and couldn't find any hard data that said either was better than the other, also the only difference between the Mt800 and MT900 seems to be the aluminum layer is painted black. On paper that would help them dissipate heat better but I question if there is any real world difference - and at the time they were 2x as much! My point being, I thing any of the higher tier Shimano offering, regardless of Rxxx or MTxxx, should work equally well. I'd base my decision on price, availability, and cosmetics. It's all good.
