What is all this nonsense before me? The only thing I know other races can do best is boast about their little accomplishments.
The greatest and most majestic of all races Eru put on Arda happen to be
Wargs. Tom Bombadil, the most powerful being on Middle-earth, is a Warg. So are the Istari--don't believe it when the books say they're Maiar.

Angamandi, time and again they come to the salvation of Arda! Who caused the defeat of the armies of Morgoth? Eönwë and a hundred Wargs. Who caused the destruction of Ar-Pharazôn's impious armada? Sea-Wargs. Who actually defeated Sauron--twice? A Warg.
Obviously, Wargs are the best.
