Statistically speaking, who is the best character in Overwatch?

So i'm looking for people to submit information for me about their over watch matches with certain characters, i only want payload map statistics (when i say statistics i mean damage and healing and deaths per game) and i want you to say which character you were using, i will then put this info into a excel spreadsheet i have made and will tell you the best hero in Overwatch. requirements: need 20 matches for each hero payload attack map (preferably won on attack) any level is fine, casual or competitive
