They both have their own physical attributes which are unique and rare, so what really makes the difference is who wants it more. Lesnar has a history of "wanting it more." He wanted to be NCAA Division 1 Wrestling Champion and he achieved that. He wanted to rise to the top of the WWE and he did. he wanted to become UFC Heavyweight Champion and he did. Brock is also tied for the record of most consecutive successful title defenses by a UFC heavyweight Champion.
Hunt on the other hand has a record of getting close but never becoming a UFC Champion or even a PRIDE Champion. Hunt is much more inconsistent. He's had 24 pro fights and has won 12 of them. He wins 50% of the time. He's also 42 years old now; his prime years are behind him. Lesnar is 38 and has taken a lot less punishment in pro MMA. His body is 4 years younger chronologically but when you factor in the punishment each has taken in fights, Hunt is more than 4 years older. Lesnar is the one who has a record of getting things done when it has mattered the most and this fight, which may be his last MMA fight, is a fight he dearly wants to win. He doesn't want to finish his MMA career on a loss. Lesnar is the hungrier man and I believe he will win it.
