Quoted from DaveH:

Deadpool is a cool game. Really nice effort, and I can pretty easily say that at some point, I will own one. However... MET is the real shit. MET is a game I didn’t like when it came out. It just didn’t have “it”. It was kind of meh, so I ignored it for quite a long time. Then after some updating to the code, I tried it again, and WOW, what a difference. By this time the LED was out, and it was all around a much better game. So one day I was at a car show reading Pinside during lunch, and saw one local for a great price. I jumped all over it, and had it in my house that day. It quickly became one of my favorite games. It is just so much fun to play, and I actually love that you need to earn the good stuff. The pressure of CIU, and the despair of trying to double the jackpot, only to drain and lose it all. Or those games when you get all the lanes locked on and blo up he score hike getting back into CIU quickly. It’s a fantastic game that isn’t going anywhere.
Deadpool may reach that lofty status, but not all games do. MET for the win.

MET is a complete game and a masterpiece. It is arguably Stern’s best pinball to date. DP is more approachable and simpler, yet is fantastic in so many ways. Either pin makes for a smart choice, but to answer your question - MET is best.

Quoted from bigdaddy07:

Totally disagree here. The hammer smashing the ball into the playfield is my favorite trick in the game. Anytime I have someone new over to play it and the hammer does its thing, they are always like "that's friggen cool". I think having the shaker and upgraded sound really adds to its effect. If you have neither, I can see how it may be slightly underwhelming.
