Canon both at their peak and best who wins in the following :-
1.H2H 2. Force powers 3. Light sabres 4. All out fight anything goes
SHE

Ahsoka could possibly take sabers. By Rebels she was skilled enough to give Vader a decent fight, and Rebels Vader>ROTS Anakin>Dooku.
She hasn't done enough to say she could take force or all out though. Her best feat was temporarily stalling Sidious's attack while her and Ezra were in TWBW.
