It may be prettier looking. I've seen many Git GUIs that are prettier than Magit.

But none of them that I've tried have ever come close to the workflow.

I can stage and unstage individual hunks, do complex interactive rebases, squash commits, break apart commits, etc. much faster in Magit than I can in other Git GUIs.

Maybe you're hung up on the "G" part; perhaps I should have just said "UI" rather than "GUI".

So no, I haven't tried that one because it's Mac only, but I'm not really seeing from the screen recordings the kind of workflow that I find so powerful in Magit.
