I dunno. I've always thought that once you cross a certain threshold the differences in power become difficult to distinguish and largely academic. Ngannou, Rozenstruik, Lewis, Pavlovich, and Tuivasa all probably hit about as hard as one another or nearly so in practical terms. You can endlessly nitpick about displayed feats where one showed greater power than the other and the mitigating factors therein (KO versus TKO, "The other guy was moving into it", etc.), but I think it's a bit silly personally.
The important part is that they're all clearly capable of hurting anyone in the division with a single, well-placed punch (and sometimes even with a glancing blow). At that point it's more about the other intangibles that accompany that power and allow it to be brought to bear more effectively: hand speed, timing, accuracy, distance management, their ability to carry that power late into a fight, etc.
Obviously very powerful,but He doesnt throw wild. He touches you,finds that range and the combinations that follow hit their target dead on exactly where he means to put it. Dead accurate. When opponent falls out of range he stops punching and gets back in range. Very calm,methodical,but with that power,it wont last long for the other guy,once he starts stringing punches together.
Its obvious too that he does not need to rear back to generate force. Even his arm punches can knock you out.
This. Also, those flurries of shovel hooks/uppercuts that he likes to throw to hurt opponents who are dipping down (either in a desperate attempt to evade or because they're hurt and in the process of falling to the canvas) are absolutely vicious, even if they're just arm-punches some of the time.
I also saw someone point out the other day that the mechanical way in which he loads and throws actually has the side effect of lifting those enormous traps & shoulders up to guard his head -- making it easier for him to roll incoming counters, something he actually did against Tai. I was very impressed by the overall defensive acumen he displayed against Bam Bam, in fact. Despite what outwardly looked like a madman rushing down an opponent and swinging for the fences, during the replays you could actually see him using head movement, shoulder-rolls, and of course the keen distance management you mentioned.
Even if he just had "average Heavyweight power" he'd be a solid Top 15 guy. With what amounts to the touch of death or close to it he is dangerous as fuck and I say that as someone who wasn't sold on him for the longest time. I think he still has things to prove inside the Octagon, but he's very, very legit and a tough out for anyone with the attributes and skills he possesses.
