Anakin and Vader ROTS vs. Dooku

No, because what your saying about his form is bullshit. Dooku was taunting him and he was playing with him. He underestimated Anakin there and then and lost more then he wanted too probably, but that doesn't change the fact that he wasn't trying tow in.

And honestly how come Vader perfected form V and Anakin did not, the difference between the two is just days?

Trust me Fishy.. Anakin and Vader combined would finish Dooku, maybe Dooku is able to defeat Anakin although he doesn't really show it in the RotS. Dooku can not defeat them both, we don't even have a clear impression of Vaders skills.

Sure we do, we saw a huge fight between him and Obi Wan didn't we?

And have you even read the points about Dooku losing from Anakin and how it was fake? Also Vader and Anakin will work together like shit and pizza... Very badly.

Sure Dooku would just let Anakin take off his hands, if he really was in control of the fight that would have never happened, it's not like he just lowered don't his concentration on the fight.

As for the new Vader, I think the dark side really enhanced Dooku's fighting abilities and with Vader it did too, I suspect form V really fitting for the dark side as it is based on strength and the dark side helping in it just like what happened to Obi in TPM and Mace uses it too.
So I think Vader was incredibly strong by combining form V with the new found dark side powers.
