I’m going with Ortiz. Cooney might have been a better boxer but I don’t think he could take those ripping left hooks to the head. And Ortiz had a better chin
The straight up, earmuffs of Cooney would be a sucker for that straight left of Ortiz, he’d measure him and walk him onto it time and time again, until he hurts and stops Cooney, or Cooney goes into survival mode and stays on the outside, where Ortiz would simply pick him off at low volume with the longer punches.
