How about someone whose fan of neither lol? An unbias opinion. Taking away chiefs initial fame and notoriety, or better yet since destiny has no noteble character like chief we need to take a standard spartan and standard guardian. Take all their skills and abilities and pit them against one another. I believe the results would be less one sided since you're not pitting a famous character like master chief against just any guardian. Most would say chief regardless of the odds for or against just because they,dint want him to lose. Let alone lose to just any unnotable guardian.
