I love how you fail to mention that Vader nearly got his ass handed to him during that fight...
Now in raw Force Power, I would give this to Vader (perhaps... since it depends), but Vader has this nasty suit that suffers from a major weakness against Force Lightning or hell even an Ion Grenade.
In pure saber ability it is hard to judge since we don't much about Malak's real abilities although as stated on his official profile he was clearly a skilled user.
Vader was also skilled duelist and eventually modified his style to fit his suit, but suffered from being much slower than he was (and don't pull that "but in this comic he moved really fast!" bullshit because in RoTJ he is clearly slow and RoTJ beats any comics/books/games in the canon department) so that's an advantage for Malak. Overall, I don't know who would win this since it depends on to many unknown factors. However, just for shits and giggles, I will submit that Malak will win.
