Out of the entire list though, I've only played Star Ocean. If you like the real time combat, and want to put the 30-40 hours or so needed to finish it, I think you'll love it. Great RPG with a great story.
I'll be the dissenting vote and say that I thought Star Ocean 3 was absolutely terrible. The voice work, the graphics, the combat, the story...I hated nearly everything about it. YMMV, of course.
With the list above, I'd go with Digital Devil Saga. If you can get past the insane random encounter rate, they are very good games.
