What is better Dissidia Final Fantasy or Dissidia 012 Final Fantasy and why give good and bad things about both games for both games please

Dissidia FF 012 would be better because it's the sequel to Dissidia FF. It includes all the characters Dissidia FF has and more, as well as new costumes, new stages, and the ability to play as the Chaos characters in story mode. Dissidia only let you play as the Cosmos characters in story.
