Jujutsu has changed how I work with git. Switching tasks is just "jj edit <change>" or "JJ new <change>". The only thing it can't do properly is git worktrees (it doesn't replicate the .git dir to the worktrees, breaking tooling that relies on git) but there is a (old) issue relating to it. Not sure on the priority, though.

Anyway, YMMV, but I love it.
