For me it's IX. It was Hirobonu's original dream. That is how he imagined Final Fantasy and it was the most fun and amazing of them all.
I also love to death VIII and X. VII got stale for me after playing it 4 times and I JUST got into XII. I used to hate it but now I'm really liking it a lot.
Fabula Nova Crystallis should have never been related to FF and I'll just leave it there.
The 2D Final Fantasies are also amazing. I love my hubbies Cecil and Locke
