I'm curious. Of those people who say rim brakes stop just as well as discs (in dry,) how much do they weigh? IOW, do discs come into their own for heavier riders? I'm a clyde, and my experience is that no rim brake can stop me as well as a mechanical disc, even in dry. Maybe all the different brands of pads I've used have all been sub-standard? If so, I need to find out what magic pad I should be using.

I personally have been in a situation of being on tour (no choice but to ride in the rain,) going down a 13% grade in the rain, and not being able to control my speed with rim brakes. I started at 25 mph and reached 46 mph, all while my (rim) brakes were on as hard as I could squeeze.
