So...

Melee: Saren's Hand-to-hand combat wins. Why? He's as good as, if not better than, Shepard. Who, might I add, kicked Kai Leng's ass several times when placed at a disadvantage each time. Bear in mind that Saren is the only opponent Shepard faced who was able to best him on even terms (See: Virmire) in any form of combat. Kai Leng is outclassed in even the most basic form of combat here.

Close Range: HMWP Pistol wins. God pistol vs a really crappy sword that can be broken easily, where Kai Leng is so unskilled as to struggle against a terminally ill and weakened Thane? No contest; Saren simply needs to maintain distance. Edge: Saren.

Long Range: HWMA Rifle wins. That palm blaster is "long range" only in comparison to Kai Leng's sword. The assault rifle can put more ammo in the air and can do it accurately from farther away. There is, again, no contest. Edge: Saren

Special: Saren wins. Saren gets this so easily it's kinda hilarious. From the incredible OPness of Warp, the ability to throw Kai Leng around like a ragdoll, fuck over his weaponry, and stun him while preventing the use of any of his talents, Saren completely, utterly dominates in this category. Edge: Saren

X-Factor Agerages: Kai Leng has a higher average somehow, despite being far less skilled, less intelligent, and less successful than Saren.

Overall: Saren curbstomps Kai Leng here. He's more skilled, is able to win without the developers forcing his enemies to make the stupidest decisions because plot, and has better weaponry.
