Well, even if you bring Moore into this, I think there are very view examples of the 1-sheets actually having better artwork. Bigger or slightly different framing doesn't really mean all that much to me.
1-sheets that I would consider with better artwork are TMWTGG style B, The Spy Who Loved Me (even this is more of a framing issue) and maybe Thunderball. However, if you look at which quads have clearly better artwork, I would say Dr. No, From Russia With Love, Goldfinger, For Your Eyes Only and Never Say Never Again... the first three of which are from probably the most important and desirable films.
