Comment by lambda

I'd consider myself an expert on Git, and I use a GUI of sorts for the vast majority of my Git work: Magit in Emacs.

It has many of the advantages that you describe; makes it easier to get an overview of what's going on, makes it easier to stage individual files, folder, lines of code, hunks, etc.

There are a couple of cases in which I need to fall back to the Git command line, but it's not very often, and I do find it substantially improves my life.
