The Ontario 498 is definitely better then the USMC kabar... The camillus USMC knife, isn't manufactured anymore, but you can buy older ones for 100-200$ and those things are tough as hell, and they are the original kabar. The kabar brand is nice but they aren't the best by any means. People often assume the brand "kabar" made the original USMC fighting knife, when actually the first mark 5 was made by camillus, united cutlery who later changed their name to "kabar" banking on the name soldiers have the USMC fighting knife, only actually made about 25% of the knives during the war. The brand "kabar" only had about a 1-3 years contract with the U.S military, and while the kabar knife has been used for decades by the military, the kabar brand was very short lived in the military. Ontario has held the soul contract of the U.S military since the end world war 2, so chances are most of the stories you hear about ka-bars is mostly in reference to the Ontario 498, or Camillus... Only 25% of the soldiers during world war 2 has kabars made by united cutlery. United cutlery stamped the name kabar on their blades, but these knives were called ka-bar before "kabar" was even a company... So in all honesty Ontario has held the U.S military contract for the manufacturing the mark 5 for soldiers for over 5 decades now and that says something. The extreme testing out military puts these knives through obviously says the Ontario 498 has held up the best in testing otherwise they wouldn't have had Ontario as the soul manufacturer for so long. This isn't to say you won't see other brand knives such as case, and others, but alot of the stories about the ka-bar knife are in reference to the ontario 498 and camillus USMC fighting knife. People ignorantly assume because united cutlery changed their name to "kabar" that they are the original manufacture of the knife, but this is far from true, they were neither the first, or the best, and definitely not the most used by the military...
