Obi Wan is MOST superior in his ANH state.
Only Yoda and Vader are as strong as he is!
Everyone else will die and decay eventually.
"Your powers are weak old man!"
"...If you strike me down, I shall become more powerful than you can possibly imagine!"
So once Dooku strikes Obi1 down, he has actually given him the victory. For the Force resurrects him. And he appears in his shining glory as a holy(force) spirit. A trick even Sidious cannot perform.
So Obi1 is the ultimate winner.
Njah, njah, njah.
