Having gone from Aluminium rims brakes, to cable discs to hydraulic discs on the MTB, there is no way in the world I'll be hanging around on rim brakes on the road bike, especially with carbon rims. In my opinion they are just that much better for braking power and reliability and in the wet there is absolutely no comparison.
I'm not a fan of carbon rim braking either, but my girlfriend (who as a former rock climber is light and has extremely strong hands) does all kinds of wet and/or loose surface road descents with carbon rim brakes without issues.
But I don't understand why people keep comparing carbon rims on road bikes to discs on mtb:s. It is not the same scenario.
On mtb:s you have much grippier tires, which makes the brakes the limiter (instead of the tires on road bikes) and you also use skidding as a technique to make turns, which most people don't do on the road.
It's not about comparing MTB to Road bike riding but a lot of people have gone through the same issues when MTBs made the transition, it is however about comparing brake systems and a lot of people through MTB or now Road bikes have made that transition.As has already been said, its about braking power, reliability, modulation and wet weather performance. Even if you are talking about outright power, my experiences are that neither Shimano or Magura at least are not over endowed with braking power and I think the limiter should be tyre traction, not the (lack of) ability of the brakes to do their job and when the brakes are powerful enough, thats where the modulation becomes important.
