if you make commits, then you are at the scale where its killer features would shine. In other words, even the most basic git usage is made easier with jj.

If you care to learn more, there's tons of posts on hn and the broader web, so I won't bother sharing any links. I will say, though, that you should use it with jjui, which is a tremendous TUI for jj - you don't even really need to learn any of the actual jj syntax because it just handles it all for you.
