Sorry, not a PS3 user, no idea how that would work.
1095 vs 5160 - both are spring steels, not all that different, and 1095 should have better edge retention at the same hardness, as should L6. But 1095 and 5160 are among the cheapest steels available and no where near the top in impact toughness or wear resistance. But 5160 is quite tough and is also cheap (as mentioned), a good steel for a 12" barong blade. Imcasa uses 1075, Cold Steel uses 1055 (= 5160 - ~1% Cr). What is impressive about the Power Eagle (other than its name!) is the length and the barong design: 12" + 26 oz + flat-ground blade from 1/4" stock to 0.05" behind the edge. The design allows that heavy weight to put a lot of energy behind that edge in a chop, and the edge is thick enough to endure stress while thin enough behind it to aid penetration. The downside - it binds terribly, just like most machetes. I can't see this blade performing much better than the Imcasa or Cold Steel (after a good sharpening) which are a fraction of the price. I'd love to be proven wrong!
The Rodent 9 blade is only 9" and isn't ground nearly as thin, indeed is a VERY different design, not a machete. That said, it's thicker grind makes it less apt to bind in wood and gives it higher structural rigidity.
As to the defects, I probably would contact that swamp and have them make it right as it clearly bugs you. In my mind, the only way to keep a company on its toes QC-wise is to call them on it when something isn't right. If you're honest and understanding, let them show you where they can meet you on the matter, test their customer service. You bought the knife, you deserve it. Just my $0.02.
