I've been a fan of disc brakes dating back to the time that everyone on BF informed me that they'd never be available on stock road bikes because there was no real advantage.
Now with mechanical discs on a cheap MTB and still Sora level calipers on my road bikes I am completely satisfied with either. If my next road bike, if any, comes standard with hydrolic discs, it's all good. I won't give it a second thought.
