Rim brakes are absolute dinosaurs in every way, there's no avenue of their use that discs don't cover, why would i ever intentionally go back to rims?

Actually, there's one - rim pads generally last years. Perhaps because they don't really do very much, and they weigh a ton.

Discs then; Feel better, modulate better, grip better, work the same in any terrain or weather, or how much or little you use them.

I'm running a 100 lb (45kg) 2,600w e-tandem with Shimano Zee hydro brakes, semi-metal pads and floating 203mm discs, with repetitive launches and slowdowns of 10-50mph several times a mile, and the brakes are up to the job.
Can you imagine trying to run rim brakes..??!!! Jesus, i'd be in a hedge in the first half mile.
