Good question. Lets look at numbers here, Arlovski has been KOd 35% of his fights, Overeem has been KO'd 27%, Andrei 15 on his record while Overeem 16. Numbers are in favor of Overeeem, KO'd less. Adv for OVereem.
Now from their fights here is what I see. Andrei gets Knokced out easier, he seems to go down from the first big shot that lands and he's out. Rizzo, Timmy, Stipe, Fedor, Nganou, Rogers, Datsik. Overeem goes or gets wobbled but usually it takes follow up strikes (most of his fights). Advantage Overeem
Who can take a harder shot?? We have seen at time both guys able to take shots and survive. Andrei took em from Big Tim 3, Rumble, Barnett while Overeem took em from Neslon, Werdum 3 and a few more and survived. But Overeem gets dropped while Andrei can stay standing. In addition Andrei survived Brown, Barnett knock downs. Overeem gets knocked down easier I will give Andrei the advantage.
Now in terms of power punchers. Andrei has been KO'd by Rizzo, Sylvia, Fedor, Rogers, Sergei, Stipe, Overeem, Nganou which are all guys with BIG power. Overeem has taken TKO's to guys like Browne, Arona, Bigfoot, Rogerio, Rothwell, Hoffman.....guys that arent known for big power. In addition to power punchers. So advantage Andrei
Overall result. I will say Andrei has the better chin. Survived more knock downs and close calls, better at being able to keep standing when hit with hard shot, and he's only been KO'd by big power punchers.
