My First Poll

So I'm contemplating a campaign setting for the Advanced Adventures line of 1e modules and wondered what type of presentation people preferred: the original Greyhawk folio, the Greyhawk gold box that came later, or the 1st Forgotten Realms box (the gray box, not the black box).

Personally, I'm a Folio guy, although I have a soft spot for the gold box as well. What do you all think? I'm leaving the poll up top of the blog until it expires.
