All of what you say is correct. git is great in many ways and not too difficult to use once you grok the internals.

But git's user interface is inconsistent, has got weird error messages and confusing terminology with too many ways to do some things.

Good thing that it has quite decent manpages which explain these things thoroughly. The UI gets the job done but it sure isn't a great example of a well designed command line.

It's rough in some ways, and elegant in others. A bad error message does not a bad UX make. Good error messages are great, but remember UX is also about hitting the important points well.
