I have a couple bikes with disk brakes, and they do have some advantages, like a much cleaner operation in the rain (no black aluminum oxide debris). But when they squeak they are annoying. They do brake better when wet, but only marginally. And in dry conditions, a modern Campy setup will brake better. On the other hand, in steep descents, rim brakes will heat up the air in the inner tube, increasing the possibility of a failure, but only if you are not rolling tubeless.
Those Campy C-Record are very nice, but they don't brake as well as modern versions.
