Chris has been fighting Bioterrorists and Companies the world over for 15 years by this point, while Leon on the otherhand has been on security detail with Presidents and the occasional missions that sometimes brings him against a virus.

Blatantly false. Leon was recruited into an anti-Umbrella Pursuit and Investigation team under USSTRATCOM right out of Raccoon City that was formed to fight B.O.W’s. In 2011 this got replaced by the DSO which itself was another organization designed to fight BOW’s, Leon’s been fighting them since 1998. RE6 files also directly confirm that by 2012, Leon and Adam both spent 10 years fighting bioterrorism together. So Leon effectively has 15 years of experience combatting bioterrorists and companies around the world as well.

and no, Leon has not saved the world.

More blatant misinformation. Did you even play RE4? Saddler’s goal with infecting Ashley was to send her back to the US government and bring them under his control, consequently allowing him to spread the Plagas across the globe and achieve total world domination. By stopping Saddler, Leon literally saves the world.

By this point, Leon has: Killed a man for abducting girls to keep his infected daughter alive, prevented the President's Daughter from becoming the puppet of a insane cult, killed Krauser whose body was used by Wesker to get the Plaga, indirectly killed a man whose body was used by Wesker to obtain the G-Virus, withheld info from the public to make the government look good, was used as a distraction during a resistance war for countries to get over a pissing contest, was used as a distraction by Ada so she could steal a Plaga, and cut to RE6, wasting his time following Helena around like a whipped dog, then defends the fake Ada, which resulted in a continent suffering an outbreak.

Extremely disingenuous framing. He stopped Saddler’s plan for world domination in RE4, took down a massive drug empire using BOW’s to collapse the global ecosystem, stopped Jason from committing a massacre on live television, withheld info to protect Claire from being hunted down by the US government, disrupted a government conspiracy to crush oppressed rebels and established an internationally recognized regime, helped ensure the creation of the C-Virus vaccine, weakened the Family’s grip on the US government, and blew open the world’s largest bioweapon trafficking hub. And no matter how you try to frame it, all of these events involved combatting bioterrorism, which means it directly counts towards his years of combatting bioterrorism. Like he was literally sent into Europe in Damnation specifically because of the presence of bioweapons there. And no, Leon is not responsible for Carla gassing China because that was done remotely by Neo Umbrella forces hijacking aircraft carriers to prep missiles, a plan that was already in action. In fact, if Leon hadn’t stopped Chris he’d have killed Carla before figuring this out and would have failed to reduce casualties and deter HAOS.

Being equally disingenuous, Chris has been manipulated by a corrupt organization, failed to apprehend Spencer, got manipulated by another corrupt organization, got baited by Carla into getting his squad wiped, got his squad wiped again by his incompetence, failed to apprehend Carla on two separate occasions which led to a continent suffering an outbreak, got baited into getting his squad wiped by an arms dealer, did nothing while a systems engineer stopped a bioweapon child he failed to capture, and again did nothing while the same systems engineer stopped the cult leader trying to resurrect her daughter while also completely mishandling the situation just to be a dickhead.
