If this is to scale, that's a pretty blunt, and it would make a pretty big difference in performance imo. That being said, with a 2s burn time and almost as much Ns as the 9M it should do a lot better than the 9M in the first few seconds of flight. To put rough numbers to it, I'd imagine within the first 2nmi or so the Magic is better, beyond that I imagine the 9M is better. With the 9M getting maybe a mile range over the Magic.
That being said, this is 100% speculation based off of the general shapes of the missiles with the known motors of the missile using educated guesses. CFD would be needed to know for sure.
