Not even close. I find that within 3-4 turns, I'm on a brew's six. Albeit slower than trying to land on the six of a 190  
so like i said. they are close 

 if youre in a zero and it takes 3-4 turns (and i doubt that its prob more) of a lufberry to get on an enemy's six, its close in maneuvering... Hence the pilot's skill takes more part in the fight than the plane's abilities against its foe...
And by the way, you use flaps in the zekes right? please say you do....
