Dooku in all three. Kun is overated. Jedi's swordsmanshop was far less advanced during hus times. Dooku survived two fights against the most powerful Jedi master in history (exdluding Luke), and many times fought some great duelists like Windu, Anakin, Obi-Wan.
As Force user, Kun had some nice feats, but I somehow doubt, that he would be able to succesfuly used his skills against other strong Forcce user.

He was far more powerful than Arca Jeth, Odan Urr, Nomi Sunrider, Ulic Qel-Droma, Vodo Siosk-Baas and any other Jedi of the time. He is also stated to be more powerful than any Sith before him. Using absence of evidence is really quite weak actually, to be honest.
