Base 16: Hexadecimal Numbers

A rogue scorekeeper in the NBA has decided, during game $7$ of the finals, to start keeping score in hexadecimal (much to the confusion of everyone else). If Kevin Durant scores $21_{16}$ points and Stephen Curry scores $2A_{16}$ points for the Golden State Warriors, LeBron James scores $39_{16}$ points and Kyrie Irving scores $12_{16}$ points for the Cleveland Cavaliers, who wins the game? (assume that no other player scores any points)
