And less fade. And less rim wear. And less chance of water reducing braking force, since the braking surface is away from the contact point. And better braking if your bike is not a standard wedgie (e.g. tandem / recumbent). And less chance of causing a tyre blowout due to rim heating (allegedly).

And less fade.
Why?
Brake fade is bad. If brakes give you less of it, it follows that they are better, all else being equal.
I agree but the implication was that disc brakes are more fade resistant (all of the other points Guy mentioned were positive traits of disc brakes), although this isn't clear by looking at the quoted section. No doubt Guy will clarify if he was instead referring to rim brakes. Again, I often hear that disc brakes are less prone to fade resistant and I wonder if it is true and why.

I see -- your question was a little unspecific. It would surprise me to find that disc brakes were less prone to fade, since they appear to have much less surface area available for heat dissipation, but there may be other factors I'm overlooking. They certainly must reduce the chances of tire blow-off due to heating of rims, but this is a different question.

That's certainly my experience. Because you have much more discretion in the choice of disc material and brake pad material than you do with rim brakes you can chose arrangements that are less prone to fade. Heat is not an issue - remember Formula One brakes work best when they are glowing red hot - with the right materials choices.

Why?
Pad compounds and steel rotors is my guess. The steel rotor means you can use a much more aggressive compound without worrying about wear. But it works: braking at 40mph on rim brakes produces a lovely smell of melting phenolic resins and no noticeable deceleration, same with discs results in Major Stopping Power.

You're doing it wrong then. The rim brakes on our tandem have done hard stops from > 50mph more than once (feature of having steep hills with a nasty sharp corner at the bottom!)
(maguras, black or red compound - the latter is the same as the koolstop salmon and is what's on it at the moment).

Ah, that makes sense, although I'm not sure it's a problem with all rim brake pad materials either.
