I'm surely in the minority here. I've been using Emacs for almost a decade now, but I just can't get into the Magit workflow. I've tried several times, but always end up going back to Git on the command line. I have dozens of aliases, shell integrations, a nice diff viewer[1], etc., and interacting with Git has become muscle memory. I can commit, cherry-pick, rebase, bisect, fix conflicts, etc., in a fraction of the time it would take me to navigate Magit's UI. I'm sure with enough practice, a Magit user could do this more quickly and efficiently, but honestly, with some custom-built porcelain, Git's UI is not so bad. Though this could very well be Stockholm syndrome after using it for such a long time...
For whatever reason, Magit's opinionated workflows never clicked with me. A part of it is the concern that it will do something weird to my repo that I'll then have to waste more time undoing manually. I usually don't trust sugary wrappers around tools. And another is the fact I don't use Emacs on all machines, and setting up Git on a remote system is just a matter of copying over my config and some shell integrations.
Also, on a more personal note, I find the cultish fanboyism whenever Magit is brought up slightly offputting. Does anyone have anything bad to say about it? No software can realistically be this infallible. :)
