There's no advantage for doing this at all. It's just duplicating the work git does for you already, but outside of git. I'd rather recommend spending some time with git to get familiar with your tooling, instead of working around your lack of familiarity this way. And when it comes to "what's an advantage of rebasing over merging" - those are two completely distinct operations that make you end up with different results, so there's no simple answer to that question (it's like "what's an advantage of bold font over italics?"). Sometimes you want to merge, sometimes you want to rebase. Once you can visualize your repository in your head, it becomes rather obvious when to use which one.
