I voted for Navarette by knockout. I understand that Filipinos have a good lineage as far as boxing history goes. But when we look at Navarette, except for that one fight wherein he goes up in weight, he has been elite at 130 lbs.
But the good thing is that there are two Filipinos rank 1 and 2 at the WBO division in which Navarette holds the belt. So in any case that Charly Suarez was defeated here, Magsayo might have a crack as well, or any champion at this division as Mark is highly rank in all governing bodies.
Plus the amount of opposition that Navarette has is far more superior than Suarez, and we all know that experience in boxing has a lot of advantage.
It looks like you're right by checking their record and comparing, Navarrete seems to have a higher KO% than Suarez.
Based on the records, this Mexican is a good option to bet with a higher chance of TKO.
Despite having two losses, it is still stronger than Suarez. I also watched their video, so I am more comfortable betting on Navarrete.
