as many of you know i have been a AVID dora pilot for almost 3.5 years....
flying the pony just for the past few weeks, i find absolutly no fear of a 190, even comming from above. i did have a great engagement with i think NORD, though i may be mistaken on who... i got him. that was the toughest fight i have seen. other than that, i think i have been killed maybe 2 or 3 times by 190's that got a shot off because i flew stupid.
conversely, back in my dora, i had quite a few engagements with some the the "better" pony pilots, and mostly we came out even, with a slight advantage to them because i am not a good pilot in the first place. i can remember some specific 1-1's that we went over and over again, i think it was grmrpr. there were others, but mainly it was about even.
it is hard to say, and i still love my dora, but i might hae to give an edge to the p51 by maybe 55% to 45% for the dora. in the end pure pilot skill, AND knowledge of both planes abilities is the deciding factor i think.
just my 2¢
