What made you a huge fan?

Versatility. If you aren't running suppressed you won't see as much gain. The ability to have reliable function with subsonic ammo through a can gives you another tool that you just don't have with the 556. At first there were no good options for projectiles, but now we have Barnes black tips and Lehigh MEs. The round was engineered with short barrels and cans in mind. I still rely on the 556 for many roles (love the 70 TSX) but like not having to dick with blackouts to make them function suppressed and short.
