As people have mentioned, Anakin's inconsistency is the reason why he's so difficult to rank accurately. And clearly yes; his performances vary based on his emotional state.
Here's where I have him in an all-out battle
In an apathetic state (e.g fighting Savage or opponents he hardly knows/dislikes), I can see him losing to TCW Maul no joke.
In his Adderall jedi state when he's focused but limits his anger (e.g early TCW Ventress fights, TCW movie Dooku fight, Oba Diah Dooku fight with Kenobi), I see him slightly above the likes of Kenobi and slightly below Dooku.
In his pissed off state when he's angry, usually at an opponent he's known for a long time, (e.g Dooku fights on Naboo both times, at the end of the Barriss fight, when he apprehends Ventress at end of S5), I have him slightly above or on par with Dooku and slightly below to on par with Mace.
In his Zonakin state, when he fully embraces the dark-side, (e.g the infamous Dooku stomp in canon after Dooku Dun Mochs him) I have him at or above amped Mace when he was fighting Sidious.
I don't believe Zonakin could ordinarily defeat Yoda or Sidious in all-out however—though maybe if Padme was raped in front of him along with Tano and Kenobi.... 😖hifty:
