This is a tough call. It was a huge shock to me when the WoB just went and the World of Ruin just raged in there! I was used to the lush greens and general pleasantries of the world of Balance but imagine my shock when the world suddenly becomes this bleak, abyss of desolation! As for which I prefer I would have to weigh up the cons. In the WoR I was stunned yet eager to see how it affected the cast and if they were all safe (especially Edgar, I freaked at the prospect of whether he was okay hahaha) and what had happened in this whole year that had past. Aside from Celes, were they alive? Were they dead? Would Celes keep her will to live? etc etc However aptly, the WoR segment dragged a bit for me and made me as melancholic and bleak as the hopes of that world.

I would vote the WoR for the shock factor alone, but in conclusion I love both. Because the antithesis of both is a core part of Final Fantasy VI.
