Which hero is the easiest to use to win the best of the game in "Overwatch"?

The one I always take as the best is Mercy: Mercy’s role is to play a huge role. All auxiliary heroes are the same, but for the best in the game, they are just behind-the-scenes workers. His level A is not as good as that of Master, but At least he still has skills to back him up. Symmetra: This black woman is not only a trap, but also a trap. His teleportation plays a key role in both offense and defense and is worth playing. Zarya: This tough Russian girl is not very popular, and she is a hero whose attack method is difficult to impress. Although her auxiliary skills are good, her popularity is low and "not fun". She is the best in the game without her. .
