It determines who is the bigger douchebag. If you 1v1 it should be fun, not because 1v1 me fgt ill wreck u. There is no single way of determining if one player is better than another player, it all depends. You can be the most skilled PvPer ever, but if you're a condescending asshole your skill means nothing. A good player, to me, is someone that is good at communicating and using callouts while still playing objectively and holding a decent K/D. But everyone has a different definition of what makes who a better player.
