I agree on this statement also. Not only does Tales of battle system I think is better and more fun, the story is also well-told and intriguing. Final Fantasy now a days aren't that fun to me, especially with the directions they're trying to make their main characters go. In the Tales Of series all the main characters have that fun enjoyable personality and they stick with it, and it never gets old. In FF the characters are either gloomy, angry, or hyper.
This is only my opinion though. I just prefer Tales Of over FF anyday. After Tales Of it's Persona and THEN it's FF for me.
