Shin Megami Tensei IV or Project X Zone?

Which of these 2 games is the best?

What i want:Animish Characters
An nice story that can keep me in the game and a more insight in every character's
life.
Many stuff to do after the main game
Nice Music

I have seen footage of both games, and Project X Zone seems to be nothing more that a cheesy crossover game with rather limited gameplay.

SMT4 however is supposed to be a masterpiece.
