I still think FFX had some of the better character development in the series, and I enjoyed the combat system a lot and the story was pretty good. My dad also got really hooked on watching me play it when I got it, so there are some fond memories there.

FFVII on the other hand had a story that suffered from a poor localization, characters with the development of a rock, and one of the worst battle systems since the NES. Oddly enough, despite acknowledging it's many faults I do still like FFVII. Possibly more than X, but I do believe X is the better game.

FFVII has the better soundtrack by a long shot though.
