I use gitkraken for two primary purposes:

1. Having a visual representation of my project history.

2. resolving merge conflicts

Of these, the first is really the only thing I really want a GUI for. I'll just have it open on my side-screen if I'm managing some more or less messy branch structure or quickly want an overview of what has been done on which branches, where common ancestors are, etc. All the actual doing of things is done from the CLI, because it's just better for that.
