Battle of the Sith duos

OK which Sith duo kicks most ass [for those sith who had more than 1 apprentice I have just chosen one]:
Explain why you think your chosen duo is the greatest:
Exar Kun + Ulic Qel Droma
Darth Revan + Darth Malak
Darth Nihilus + Darth Sion
Lord Kaan + Darth Bane
Darth Sidious + Darth Vader
Lady Lumiya + Lord Flint

Nihilus and Sion.

Probably Nihilus and Sion because of the drain and Sion's inability to just die. In terms of force abilities and saber combat I'd go with The Kun and Revan duo.

Nihilus and Sion would beat any other duo in a fight.

Good point and after a while (and a few choice drains) Nihilus won't need the Meatshield...

Edit.

Nihilus and Sion only due to their ability, otherwise Exar and Ulic. In saber skills, it would be Sidious and Vader.

Saber skills, I would say Exar and Ulic.

Nihilus and Sion wern't Master and Apprentice though.....Traya trained both....

Sidious/Vader take this, their the only one that wiped out the whole Jedi Order within 15 Minutes of becoming Master/Apprentice

Nihilus would be wiped out early on, Sion, too. I'll be shocked if Revan couldn't take them

I don't see Revan taking either personally, except possibly Sion (his link to Traya, could make Sion lose his will).

Revan was the strongest of the Sith from Malachor and was apparently familiar with the force drain bit.
