It may not make it fundamentally better, but it might make it easier and more pleasant. That’s what jj does for me; my basic workflow would work in git too, but it’s just nicer and easier. Which I would not have guessed, as I was very comfortable with git before I switched.

In your case, jj’s ability to slice and dice commits is really nice; jj split is built in and works similarly, but you also have other tools too.
