The Count brings home all rounds, pretty much every time. He's considerably more skilled in the art of handling a lightsaber, noticeably faster, can handle Malgus' strength without any noticeable issue, and is a more powerful, knowledgeable and masterful Force adept. The only thing Malgus really has going for him is durability, which by itself will do nothing more than prolong the fight rather than grant him a majority. He might win a couple of rounds if he gets enraged.
