Like? This isn't explained, I'm curious on why I would want to use it, but this is just an empty platitude, doesn't really give me a reason to try.

Hi, author here. Since the target audience is people with little to no Git experience, a detailed comparison would not make sense. I did simply make that claim because the weirdness of Git's UI is usually justified by saying how powerful it is. So this statement is just intended to ease the readers mind that they're not missing out on power by choosing a tool that's easier to learn.

I suppose I want the article written for the experienced developer, convince me why I should try something different than the huge defacto standard that is git. I'm totally open to trying something new, but need a compelling case.

Beyond `jj undo` everything else in this thread feels just as complicated as git.

A couple of them seem more complicated, like the example further up on the page for postponing merge conflicts. In git I'd just abort the merge and do it later.

I also found the exchange about named branches funny, that ends with:

> Ok, you need to call `jj bookmark set -r@ XYX` (or `jj b s -r@ XYX`), so what?

Apparently this is excusable, but people like to complain about git's commands being too obtuse - as far as I understand the git version is "git checkout -b XYX", right? (Or I guess "git switch -c XYX" with the new commands)

The difference is actually worse than that. There is not the regular git equivalent, because this step is just done implicitly for you, normally. That is, with jj, just because you had checked out the head of main and then you added a new commit, doesn't mean your new commit is now the new head of main. `jj bookmark set -r@ main` is the way you tell jj to actually advance main to your latest commit.

But you are right - `git switch -C main` would be more or less the equivalent in git if you were working in detached head mode, which is how jj normally works (note the `-C`, not `-c`, to forcefully update main to point to this commit).
