No they aren't, but when there's a significant difference between two players who have the same role in their teams, that usually is indicative of skill. It wouldn't matter if GuardiaN was just stat padding with exit frags, but he isn't. Both Kenny and GuardiaN are making impact frags. Difference is GuardiaN has to carry his team all the time, with at most one other player stepping it up, while nV is a team full of superstars.
Who won the major is irrelevant. That's like blaming KennyS for not winning a major with Titan. Was KennyS the best player in the world for a while around late 2014/early 2015? Absolutely. Did Titan win any big titles? Absolutely not. That is on his teammates' shoulders.
Remember ESL One Katowice? GuardiaN was one of the top players there, KennyS didn't even qualify due to his shit teammates. Same situation now, but in reverse.
There is no argument as to who performs better. You're just a delusional fanboy who denies numbers and links to old highlights of antieco frags. You have no argument of your own supported by solid facts because there is no rational argument, your conclusion is just wrong.
KennyS is not a god anymore, just a very good player. He hasn't been the best player in the world in nearly a year now.
