And we can't rule out the Adeptus Custodes,they are infact the Emperor's Finest. Well, the Adeptus Custodes are unfair, in the Garro audio books, it is said that even a Primarch would hesitate to fight a Custodes, and Valdor defeated Horus in a sparring match.

Also: A Custodes head-butted an Emperor's Children bareheaded and the EC's helmet buckled in and gave him a brain aneurysm, all the while the Custodes didn't feel a thing. (Trying to find the source, I think it was one of the White Dorfs, but no clue)
