There isnt any benefits in git over SNV for PCB. Stop thinking like a programmer, and just use SVN.
I totally disagree!
Let me rephrase your statement: there isn't any benefit to using SVN over git for PCB work (or Altium projects, more generally).
Unfortunately, both are rather poorly suited to Altium projects, since most of the files are a binary format that doesn't give you any info whatsoever just to look at it in a repository browser. To get anything out of either of them, you have to be pretty aggressive with commit messages and comments, which basically no hardware designer I've ever met is. But the advantage is HUGE when you realize there's a design defect or anomaly and you need to figure out how, when, and why it got there.
And SVN and Git use totally different philosophies for how and where to store data, so the advantages of one over the other really have little at all to do with what kind of project you're controlling and much more to do with your workflow. Personally, I find it WAY easier to move through projects with Git over SVN, for a whole bunch of reasons, even if you leave behind the fork/pull request model that software devs often employ for code review reasons (and which breaks terribly when your main design files are binary).
Of course, there's mostly no advantage to using an altium-internal interface rather than something like sourcetree or command line. The only real reason I want a built-in git client is for easier comparison between revisions (rather than having to go extract a copy of the old manually, then open both manually, then compare). I guess having source control status on each file in the list is ideal, too.
