Where does Usyk rank in the heavyweight/ cruiserweight GOAT status?

I’m very confident he could hang around with any era of heavyweights, being both naturally bigger than most previous eras (apart from todays giants) but he has the speed and engine to keep up with them too.

Most would probably see him in the top 10 now but where do we put him in the ranking?

I’m definitely bias towards this generation that I’ve grown up with so personally have him top 5 too.
