Comparisons are impossible and ultimately pointless without dueling. If you really want to see who is better fight someone like thirty times in a DA in random planes and see. Of course, most of the time the fight between very good sticks comes down to who missed the shot, who made the good shot, who flew a little better in that given fight, all variables in which vary based on a given day, your rust factor, how long you had been flying that day prior to the fight, if you just awoke from a nap, how focused you are, if you had your V8 juice already, if you got laid the night before, etc. It would take hundreds of fights spanned over weeks of two top guys who both feel "at their best" to determine truly who is "better". Since this is a game, there is no incentive for this level of dedication.
Take for example my fights with dedalos, when he was rusty and I was "sharp", I thrashed him in the DA, it wasn't even close, yet months later when I was rusty and he was relatively sharp, he thrashed me.
