I've only played Type-0 & 13, but like them both a lot. High recommendations to both, although 13 has serious linearity issues, I like it, and that's rectified in the latter two games of the 13 trio, which I also like. Type-0 doesn't have the greatest plot, imo, but I'm in love with the gameplay. Can't speak for 10 or 7, though.

I've only played 10 and 7 and I honestly say 10 if you like more classical turn based games. I had a lot of fun with that one.

Final Fantasy VI, because it's the best.

Now serious: pick 7 or 10 if you didn't play either and don't mind aged graphics and turn-based combat.
