In my opinion the answer to your question is an easy one, which band do you like the most? After you answer that question, buy that game. Both games are obviously great so you can't go wrong either way. Every MET owner is gonna say buy MET, and every AS owner is going to say buy AS. Also if you were blown away by AS the first time you played it, i can tell you that it gets better every time you play it. I am addicted to it big time now and when I very first bought it I thought it was just ok.

For me personally I tried MET twice and I just don't care for it that much. I think it's because I'm just not a big Metallica fan though more than anything. It's hard to enjoy a music pin no matter how good it is if you don't enjoy the music. Some other advice I can give you is, don't worry about what other people rank MET, buy whatever is the most fun to YOU, and only YOU can decide that. These are both very good games, play them both and decide for yourself.

I'm actually not an AS fan either that much but it's more my style of music. After owning the game now though I find myself really enjoying the AS music. It's great music for pinball.
