I tried it after using Emacs Magit for about six or seven years, and jujutsu is really easier to use than git and useful if one wants a tidy public history of changes (Linus Torvalds recommendations on that linked here). Plus it is fully compatible to git as backend - other contributors will not even note you are using it.
I don’t have experience with Jujutsu, but I always have the same problem with these alternative frontends, which is that I’d still want to be proficient with the original. If you need to look up how to fix something or you want to help others in your team or you want to script something, then the language to speak is simply the Git CLI.
And I don’t feel like I even use the Git CLI enough where a different tool could be so much better that it’s worth learning both.
Obviously, your priorities may differ, but yeah, that’s just always the reason for me why I prefer the Git CLI, even if it were objectively more difficult to use.
