Povetkin. Better fighter who's beaten better fighters than Ibeabuchi who has become a boxing bogeyman.
If Tua isn't stopping Ike, Povetkin has no chance. Povetkin would not be able to keep up with Ike's output, power and full body attack.
Two of the best fighters of the 90s and early 2000s. IQ would blasted that fraud the **** out. The right hands IK ate from Tua would leave that PED cheat twitching on the canvas.
Ike's best win is Byrd. Tua was another hype job, just look at his close fights with Jeff Wooden, Rahman X 2, Maskaev, etc Tua lost every time he stepped up.
Many fighter were way more skilled than Tua, yet it didn't prevent them from getting blasted the phuck out. The same would have happened to PED fraud, who is no Floyd Mayweather when it comes to defense.
Povetkin does not have anyone on his record remotely close to a prime Byrd. Isn't it funny that PED cheat 10 years later went 11 rounds with a guy IK blasted out in 5.
