There's definitely been a lot of UI fixes in the Git command-line client. I know because I wrote some small number of those patches.

There's also cases where Git's was and still is top-notch, e.g. in the use of terminal colors by default, and opening a pager for you smartly. Both of those were cases where Mercurial trailed behind for a while, although I think now it's caught up in that area.

I concede that Git's command-line UI still sucks in a lot of areas.

What I was pointing out with the "Repository Formats" reference is that one shouldn't conflate deficiencies in the underlying formats with UI deficiencies.

The latter is easy to fix, and the git command-line client doesn't have a monopoly on fixing those things. There's plenty of other top-notch UIs for Git. E.g. Emacs's Magit, and GUI clients like GitKraken, Sublime Merge etc.

Whereas the inverse isn't true. You can't really build a client like Magit on top of CVS.
