Best MOS? If you could re-class to a different specialty, would you and why?

Apache Pilot.  No explanation needed.

Good question Ben.  I served in the USMC as an infantry officer (0302) during peacetime from '83 to '88.  Looking back I would not change a thing.  I served with some great Marines and have many fond memories of what we accomplished together.  the passage of time has helped mellow my memories of the not so pleasant experiences and I see them more clearly.  Thanks for asking.

If I was in the Army, I would try out for SF. I hear so much about them, even being in the Marine Corps. I'm going to try for selection into MARSOC next year for some good livin'.
