It's quite a common opinion that git (while a big improvement on what came before) still has plenty of rough edges, particularly with regards to the user interface. At the same time, there's also a significant barrier to entry for a new version control system with all the tooling that's built up around git over the years, particularly if you want to try it in your workplace without migrating the entire company.
jj is one of the latest round of git-compatible version control systems which allows you to have a better experience locally, without having to abandon everything that depends on git. I've been trying it out now for about two months, and this post shares some of my thoughts.
