final fantasy 7 introduced JRPG's to me, before that game JRPG's were niche in Europe, so i didn't notice them until FF7, the game was great, and it will always have special place for me as the game that introduced JRPG's to me, but i just plain love FF9 more than FF7.
I never really liked cloud, i thought sephie was cool though, FF9 was just more laid back and it was not too serious, the battle system of both games were equally good, no complaints there, story wise, both games had good stories, maybe FF7 had slightly better story, i think FF9 had better characters, each character was unique in battle, unlike in FF7 were you could make all your characters the same with materia.
Overall i just loved the medieval look of Final fantasy 9, and the art direction was awesome, the game still looks amazing, can't say that about FF7.
Edit: i just forgot about the music of these games, FF9 has the best sound track in all of Final fantasy games, the music really captures you the moment you start the game and you hear the main title screen music, it wont let you go until you beat the game, it still wont let you go after you beat the game as the tunes will stay in your head for months or even years.
