I have been convinced by the sales pitch https://evmar.github.io/jjtut/pitch/ I will give a try to jj!

By this point this is probably the fourth jj tutorial I have read. I haven't dabbled in it (yet), but this appears to be one of the straighter ones. Meaning not a lot of fluff, a well thought out ordering of lessons and well suited for people who come from git.

One thing I miss is the whole pull/push workflow, but for the rest this appears to be a very good resource.
