There really isn't anything special about m4. The only reason people say m4 is great or "og" is because a group of sparrers constantly hype it up. If Famas or default were hyped up that much you would see them talked about the same way
Like I said. Once you actually start using it, you'll be like "Dang I totally love this gun".
