Breaking Bad is a completed show where as Game of Thrones is still being aired and will probably be that way for years especially since the book sequel isn't finished yet. Knowing that, I'd personally start with Breaking Bad as there'll be more to watch when you decide to follow up on GoT.
While you make a good point, I'd recommend he gets done with Game of Thrones first because there is a much higher risk of him encountering spoilers than Breaking Bad.
