Hands down one of the best features in jj is undo. In Git, undoing things is always a bit of an open heart surgery, with different commands depending on what you fucked up. In jj? Just a simple jj undo, done. That alone is a killer feature. Then having the whole thing being kinda agnostic by design to the backend system, that is also a sweet spot. I can comfortably use jj locally without any of my teammates knowing that I use jj instead of git.
