I will be predictable and say IX is my favourite. A Place to Call Home is one of my favourite FF tracks, and like some people have said about their favourites, it just fills me up with nostalgia and good feels. VII and VIII are cool for similar reasons, though to a lesser extent for me personally.

I will agree on the dislike of the look and feel of X's menu, although I will say that as a frequent soft resetter, I appreciate the fast startup.
