Beat 7 & 8 completely, got most of the way through 9...just wasn't as good after having played the same type of game two times before. I happen to like the story in 8 a whole lot, but I like the characters in 7 much more as well as the music...
 
Also of note, FF7 introduced me to the world of RPGs so it's saying a lot that while its one of my favorite games, I enjoyed 8 even more.
 
FF5 & 6 are also on the PSX/PS1, but by the time I got around to playing those games.. I was really bored of RPGs. Chrono Trigger changed all of that, it remains the best RPG ever made.. a record yet to be broken.

FF Chronicles would go here because it had Chrono Trigger on it but that doesn't count.
9 - Best FF game, including 6 (yup)
FFT would go here but I guess that doesn't count?
7 - Better than average FF game
Poop from a butt would go here but that's not a video game.
8 - Terrible and likely the worst FF but I've never played X-2 or 13

Tactics /thread

FFT > 9 > 7 > 8

To be honest I rather not rank them, there are a few things I don't like from each of those games, for example I like the world and style of 8 over 7, while I like the combat and characters/sidequests in 7 better than both 8 and 9, but 9 was the most satisfying game out of all with charming characters. FFT is probably the most likeable game interms of combat and gameplay, but I certainly enjoy other games' story and characters much more. I hate 8 the most interms of characters and development, did not like the combat system that much, though it doesn't bother me, so it's at the bottom of the list for me.

It's still a great generation for FF games nonetheless.
