There is no "best." After a certain level, you're just splitting hairs between exceptionally skilled pilots; any of them can beat any of the others, and any of them could lose to any of the others. There were nights where I absolutely destroyed Drex, and there were nights where he more than returned the favor. Either one of those nights, both of us probably could have beaten 99% of the rest of the MA in a straight up duel.
So rather than talk about "the best," consider instead a group of the best pilots. These are "the best" -- not an individual, but a group.
