I like DBZ more, just cuz I been watching it since I was like 10 or 11 and I only played 1 final fantasy game, its a tough decision though cuz I love the imagery and the storys In the FF games but DBZ has just been something I enjoyed since i can remember.

DBZ's games could be a lot better though, FF as a game is better than DBZ cuz im not into 1 on 1 fights, I like the way FF's fighting system is. but yeah thats my two cents i vote for DBZ
