magit (for emacs) is quite good. But I still only use it for browsing around mostly, or single-file commits. For serious work, I start with git status, and then git diff all the changes, and then group them and then commit then in groups, then pull --rebase then push HEAD:good_branch_name (by the time I've done all the above, I have a better chance at a good name than I do for the first commit). Then over to PR land, where we have "ff if possible and delete source branch."
