Never played Met, but i dislike their music so it could never be my favorite Stern, as i could never never own a TSPP (i hate the theme).
i have played many sterns as lots of pinball fellows here and my favorite are TWD LE and LOTR by far. i also like X-men LE, Tron, GoT, Aersomith, ST. i regret to not have played yet an IM. One of the way overrated in my opinion is ACDC, i hate this code, boring.
