For now, I think Warcury is stronger. He showed a very powerful supreme haki and his defense is overpowered, but Sengoku might have some potential that hasn't been revealed yet.

Misclick. Warcury wins cause of regen.

Warcury because gorosei level is way above admiral level

If sengoku has acoc he wins if he doesn’t then my money on warcury because his durability is insane and immortality
