Starkiller struggled against ANH Vader. His Force powers aren't enough to defeat Dooku or Hero, he might just get a small adge at best.
In sabers Dooku can possibly solo them both.
In all-out Dooku takes this with hight diff.
As a duelist ? Of course. He was worse duelist than Anakin Skywalker. Means he is also inferior to prime Kenobi, If not, there is no point in calling him ''shadow of his former self.'' Or Lucas's statement of seeing prime Jedi in action.
But he also became much more powerful in the Force than Anakin ever was.

And still, he lost to Maul. His TK level wasn't even near to that of Yoda or Sidious. He couldn't everhelm TPM Maul with his Force powers, and ROTS Anakin is equal or posssibly better in tanking Forc attacks then TPM Maul.
Nah he is not, he stalemated with Obi-Wan in force contest, he get hit by force wave from Savage Opress (just like Obi-Wan), he get force push from Barriss Offee who is nearly average in the order, he get force choke from Ventress (just like Obi-Wan), he also get stomped by Dooku with the force twice.
Vader wouldn't get none of this attacks or he wouldn't stalemate with Kenobi.

Marek still rapes the Zero of Tython with the force
