I doubt that you will feel much of a difference between the two
assuming your cable, housing and pad set-up are the same. Technically
dura-ace has bearings in both pivots were as ultegra has a bearing
only in the main pivot. Other than that it is mostly material
difference, finish, and a small amount of weight that separates the
two brakes.
