My love for final fantasy is just too big to make me ignore the "Newer" ones, but honestly , I enjoyed every final fantasy I played, and I played/watched/read ALL of them, including spin offs, Anime, books ...ect ect, ALL.OF.THEM, and I am kinda proud to do so 
I've once wrote a huge thread like yours about my experience on every single final fantasy game and asked people to share their experience, of course without the lists and "Final Fantasy (Something) IS THE BEST GAME EVER) , honestly, I don't have one favourite, because they're way too different from each other, every game has its own charms, but if there is one thing I dislike about final fantasy , its the fanboys, I really, REALLY dislike the fanboys, they make me want to stop liking the series instead of liking it.
