MET although I'm a huge fan of the new GB. MET, much to my chagrin when it came out, has become one of the greatest player machines ever made. The rules are so deep and the shots are just hard enough. Add the fact that they will probably stop producing them very soon and it all points to MET for me. However if you are a casual fun player and just want a machine friends can walk up to and play GB might fit that bill. I've only played it once and it was on preproduction code at TPF. (I have it on order and can't wait to get it) who knows what the code will be like on it but on the surface it could fill the later reason I gave you better.
