Both are really good fan layouts. Both are Lyman coded games. Afm is one of Lymans first and Metallica shows how his rule sets have matured. Fun factor is there on both of these games though. You can't go wrong with either, but I think it's a lot easier to rule the universe (which is do regularly on my afm and the outlane posts are actually pulled out of the game) than to get to encore (which I've never done).
