The Alfine IGH feels like an absolute boat anchor in the back wheel compared to the SRAM group set. It's so much easier to get up to speed and maintain speed with the X11, and I much prefer riding it because of this. That said I've had no reliability issues with the Alfine 11, other than iffy shifting that I fixed by dumping the polymer coated Dura Ace shifting cable that frayed quickly and stuffed up the shifting, and replacing it with a 105 Optislick shifting cable.
