for me important argument in favour of JJ over Sapling was "first-class conflicts" - JJ stores conflicts in the history and allows you to resolve them later, while Sapling forces you to resolve conflicts at the point when they happen
If first class resolution is done right, then instead of project generators we can just create sample projects that people fork, and when you make breaking changes or add new startup config to the project, you update the sample project(s) and people can pull the updates. Once you resolve the conflicts you’re done until the next change, at which point your repo remembers how the last conflict was resolved, and doesn’t ask you to redo it.
This is why jj is on my todo list. I’m not calling it jujutsu no matter how much someone pays me though.
