Yep. I’ve used darcs for at least a decade. The mental model is just so straightforward, I simply never wrestling with it. It does exactly what I want with very little thought. I’ve transitioned to git this last year and my head hurts constantly.

Things that used to be trivial are now unsolvable (by me at least).

The darcs ui was a complete joy. Interactive but super fast. Incredibly easy for new uses to learn.
