Quoted from libtech:
No difference in the game both are the same quality, actually Ive seen more issues on the older ones, but thats not why - I just prefer the new head with the speaker grille art is all.
Haha . Ya to each there own for sure , but I have played lots of games on both machines and would prefer to play older version . Every time I play one and say wow this thing plays awesome its always a first run . I have played brand new out of box Met pro in the last couple months and they don't play as good . They seem to not hold up as well either , I see lots of new runs that are beat where the older ones are mint . Just my opinion .
