Four generations of Huo Ying and Blackbeard, who is better?

Different dimensions are different. Personally, I think it is four generations. Black beard's ability except demon fruit is basically slag. The fourth generation of blink belongs to space ninja. Except for a little ability, other black beards are not as good as the four generations (and as Huo Ying, there are more than 1000 kinds of ninjas, which makes black beards dumbfounded). Remember to give points if you feel good.
