I'm a huge SRAM fan because this is the second time they've taken care of me when I needed it. The first time I was totally honest with them and told them that I broke my left shifter in a crash, I didn't have the money to buy a new one, and they hooked me up with a good crash replacement deal. Cost me $80 total to get it fixed.

I haven't seen anything to make me think that Shimano's are any better or worse than SRAM. I do think that SRAM has killer customer service and that's important to me.
