My entry level road bike (2007 Sequoia) had really poor brakes. Dirty roads and wet conditions, like puddles from sprinklers, caused a slurry of abrasive junk to be ground into the rim. Although the brakes are way high from the road, the rim is not and there is nothing but wind and gravity to clean off the rim before it is pressurized.
If I wanted to ride in winter, snowy icy winter, rim brakes are just inferior to disc. I found a deal on a Straggler frame and put BB7 brakes on it. I have had to learn how to adjust the brakes, and that was a small price for superior stopping.
If weight is everything to you and you are not overweight, then rim brakes weigh less. I intend to stay with discs for future bikes.
