The RD-9100 Dura Ace derailleur is silky smooth. It will replace my existing RD-9100 at some point. I love Dura Ace components because of their precision. Are they worth the monetary differential as compared to comparable Ultegra components, probably not for most people. I am at a crossroad. I love my 2001 Litespeed Vortex but it cannot support disk brakes. My current R9100 11 speed drivetrain performs exceptionally well. My concern is that 12 speed Dura Ace only comes with disk brakes which my frame cannot support. My Plan B is to acquire replacement parts while they are still available including multiple sets of cogs, chains, big and small chainrings, Right shifter and derailleurs to allow me to maintain my current configuration. I will probably do a mass replacement in the future even if some components are not compromised.
