Had a Met Pro, very fun game and good shooter. After awhile it kinda became a wood chopping fest and sold it to make room. Don't really miss it. Currently have IMDN Pro and love it. I like Maiden more than JP, even though JP has more complex rules. Thinking about selling or trading IMDN Pro and upgrading to a premium/LE one of these days if one comes around. My Pro is pretty locked in and plays great, and the Premium/LE mechs can take some dialing in to make them reliable. Trying to decide if the juice is worth the squeeze on that. Metallica definitely has better music than IMDN, but the game play and rules on Maiden are preferable to me. That said, they are both some of the best titles Stern has made and you can't go wrong with either or both of them.
