I wish I could say Gordon Freeman, but Booker has powers that would destroy Gordon. His Hazard suit would only prolong the fight. If gordon had the helmet to his suit, then maybe he'd stand a chance, but the lack of a helmet just leaves him too exposed. Booker at least has a regenerating force field of sorts.
If Booker didn't have any powers though, then Freeman would win hands down.
However we're just going to have to settle with Booker DeWitt winning this one.
