Why's Edgar called the worst brawler in the game?

I recently unlocked Edgar and is in trophy rank 20, he's the best brawler I've played. I am newbie so don't know much about the game. I have surge, max and buzz on trophy rank 20 too, but Edgar is the best, easiest and fun brawler I've ever played

I don't understand how he's the worst brawler in the game
