Well, if its Vader (pre-suit) then I think he can take it... Because he already took Dooku, and if you want reasons on why/how he could beat Maul... then read my battle:

People have highly underestimated Darth Vader. On Wikipedia here is what it comments on its talents.
"Darth Vader is a brilliant strategist and one of the greatest pilots in the galaxy. Vader still possesses his former persona's amazing engineering skills, having overseen the design of the TIE/Advanced fighter. His talent with the lightsaber is legendary. All of these skills are secondary to his incredible mastery of the Force."
Now from this we can tell he's way past Darth Maul...Dooku would be a strugle, because his Mastery of Form II, but Dooku wouldn't be able to tire out Darth Vader like Form II is made too do, because of Vader's Form V. Here read what it says about Form V...
"Form V maintains its existence through having sufficient defensive skills, as derived from Form III, but channeling defense into offense. The example is commonly used that while Form III combatants effortlessly deflect laser bolts, Form V practitioners excel at redirecting the laser bolt toward the opponent. This simultaneously defends the user and efficiently injures the opponent. As well, it employs a basic form of Form II's parries, allowing the user to parry the attempted attack, and counter it. It is different from Form III in the fact that practictioners of Form V will press the assault, using wide, sweeping blows in an attempt to overwhelm the opponent with brute strength. The aggressive philosophy of Form V is the source of many a Jedi's disapproval.
Vader also created his own variant of Form V, where he would use only one hand to strike and defend, and have the other held casually by his side. This can be seen at the start of the duel in The Empire Strikes Back.
With the aggressive but yet refined movements of Form II and the highly defensive postures of Form III, Shien / Djem So has been proven to be an effective style."
I say Darth Vader takes this one...With the suite.
