Anakin had an immense Vong kill count up to Star by Star, including killing them with less than ideal circumstances in his favor. I,e killing them when on the run with a sick Mara on Dantooine, killing them while starving/weakened in Rebirth, and slaughtering ranks of Vong Slave soldiers and of course holding his own against Jacen in a duel. His dueling feats impress me more than a mere sparring match.
You posted some impressive feats wayy before his prime, but in the Edge of Victory series iirc he was capable of uprooting a massive Massassi tree, blasting a durasteel door in Star by Star, and blasting ranks of Vong Slave soldiers. His force potential would also make him just naturally more powerful than Saesee. For what little we've seen from him even as a teenager, he simply has better showings imo. He wins in a good fight
