Some are better than others, but I honestly enjoyed every one except for Graces F. I thought the characters were all boring and lacked depth except Hubert and Malik, plus the story was kind of weak. But its all a matter of taste when it comes to JRPG's. I didn't like Legendia's attempt at 3D, but the interaction between party members is priceless.
I want the PSP version of Eternia bad, I have it on PS1 though (Destiny II lol). The few copies I've found all look bootleg, like the cover art/book look faded like they were printed at someones house.
EDIT: hell yeah man, I'm perfectly happy to keep playing my PS3. Thankfully RPG's don't push hardware limits that often
