I've tried out Blue Dragon only but I liked what I played thus far. I guess it would most closely resemble something like FFIX in art style out of the three you mentioned even though it in reality looks exactly like Dragon Ball.
As far as other JRPGs coming out this year on 360, Atlus is publishing both Operation: Darkness and Spectral Force 3 on the 360 exclusively. Spectral Force 3 is due at the end of March. Unfortunately here's the Famitsu scores for both games, so I probably wouldn't anticipate masterpieces:
Spectral Force 3: 7, 6, 6, 7=26/40=65%
Operation Darkness: 6, 6, 6, 5=23/40=57.5%
Luckily you'll also have a late 2008 release of Tales of Vesperia, a 2009 probable release of Infinite Undiscovery and whatever Mistwalker(Lost Odyssey/Blue Dragon developer) is cooking up next.
Tag: Became a freaking mod and a complete douche, coincidentally, at the same time.
