You might want to try Sourcetree if you haven't already. I felt the same way about Git GUIs for a long time, but Sourcetree actually does a good job of getting out of my way, and has a very nice commit history tree viewer to boot.
I've found Sourcetree to be way too slow. My team is currently using the GitFlow model, for various reasons, and that involves switching between branches fairly regularly. It also means that any commit to master involves a lot of steps. From the command line, this isn't a big deal because each of those steps takes a half second or so, but Sourcetree multiplies that by an order of magnitude, and the Sourcetree users are nearing a point of mutiny.
I dislike SourceTree precisely because it uses git terminology. Git’s terminology is bad enough, but it completely breaks down for me in a GUI, because I expect that GUI’s conventions there. For example, on the Mac (as in English, I think), a command named “Remove” removes an item from a containing item. “Delete” also destroys the item. SourceTree, however, uses “Remove” for “git rm” because Unix thinks “remove” destroys items.
To make matters worse, what in a Mac GUI would be called “Revert” or “Discard Changes” is called “Discard”, something that, to me, feels more destructive than it is.
End effect? We have “Discard” being less destructive than “Remove”, while, to me, it feels the other way around.
(I may remember this wrong, but if I do, I think that’s a sign of the problem of not following platform conventions in your software)
