I had the Versus Guide for FF7 back in the day, and it was definitely the definitive guide for that game, it went far more in depth into the side quests such as Chocobo Breeding, and the Accessories, then the official guide. I do believe the official FF7 Guide (Is that the Brady one?) had a recent reprinting, as I've seen it on the shelf at Borders at least once in the past few months, so if it was worth anything, it's not anymore.
