I often use Sublime Merge to reword commits (edit commit message, even other branches, the entire log is visible), or to split up commits (it undoes the commit and you get everything in the working directory), so I’m not sure if his comparison table is entirely correct. (At least from a user point of view I can easily edit or reword).

One other nice feature of Sublime Merge is the squashing of two commits, ignoring the latters message (as a fixup). Not sure how to do that in one click or command with cli git…
