I voted for UD Black. I love 2010 Panini Classics Basketball. I love Bowman Chrome Baseball cards. I love Panini's Hall of Fame basketball. But when it comes to higherend product, UD does it right (The Cup, Exquisite, Ultimate, SP and Black).
I can't afford it... but I voted for UD Black too.
@ Fuji, I hear ya Fuji. UD Black is expensive, but all the product lines in the poll are expensive.
