I enjoyed FFXIII. I know a lot of people liked FFXII, and I did like the setting and most of the characters, but dang, if it wasn't terribly paced. And the battle system was mostly boring. I thought Xenoblade did a better job of creating an MMO-style battle system that sped along more quickly.
Of course, I think we're all weird when it comes to FF games. I actually thought FFVIII was the best one on PSX. I didn't like FFV much, but really enjoyed FFIII for NES. I was disappointed by FFVII, coming off of Chrono Trigger, but it's a good game, and FFVI sits at the pinnacle of the series for me.
(For the record, Chrono Trigger is still my top RPG. A few games have tried to unseat it, and came close, but it's still up there.)
