Avids are simpler than all that parallel push stuff from Shimano (which seems to offer minimal benefit and causes screeching). Avid 25's (which I run) are lighter than Shimano XTR and work just as well if not better.
Probably most difference is the pads - they suddenly felt lifeless after I switched to Aztec pads, but recovered when i went back to Ashima.
