lol, you have to be joking right?
Pacquiao hits much harder, it's not even close. Pacquiao has a huge amount of energy and snap to his shots that Conor simply doesn't, as well as much better technique, balance, weight transfer etc.
3 people who have sparred or fought Conor - all significantly smaller no less - stated his power is average, nothing special at all.
Then pretty much everyone who has fought Manny says he hits like a truck, including Mosley who has fought some big guys.
Pacquiao feints were sending Floyd halfway across the ring, yet against Conor he just plodded forward without a care in the world, like he was sparring a day 1 novice.
Here's Pacquiao's left cross.
And Conor's.
