That's just pure crap Dalton, the Spitfire was a relatively poor ground attack plane and suffered badly when it tried that mission.
Yes it was poor. It did not take damage very well. Handled horribly damaged and had an inline motor that could fail with minimal damage.
And pointing to Lemkes success is again based really not upon his ability so much as that of his flight wing. Imagine how much easier it was to rack up the kills when you flew with a dozen or more other fighter pilots all trying to get you into the kill position. To be significant, you need to quote his unit's kills and losses
I looked at squadron kills once for the Luftwaffe and they were huge, but it got bad at the end of the war against Jugs and Stangs. Most of their 109's went down due to landing and takeoff accidents, not battle losses. I'd have to pull the links again. But what you're argueing is not consistent with reality by 1944. The Germans were always outnumbered and they used the Schwarm technique the same way the Allies used the finger four. I'm sure you're well aware of the Nowotney Schwarm and JG54's huge across the board successes. As pertains to Lemke specifically he didn't take command until 6.23.44 and by then he'd already downed his last Spitfire. (There is a discrepancy in the kills in this link) It doesnt' mean he didn't lead a Schwarm. It doesn't mean he did either. My guess is he was number 1. He obviously had a good eye.

The plane that won the war was the Jug. Theres little doubt about it. The P-51 was probably a more dangerous dogfight adversary, but what the Jug did it did very well and it did it all. P-51's couldnt do the ground work either. They fell out of the sky in that role. Leading Mustang ace of the war was killed in that endeavor. They say his own AA got him. I seriously doubt that, but thats another story.
Spit IX was a pig under the high engine load, especially when up motored. Focke Wulf were far too much plane for it. 109's too role specific for it. I have no idea where you're coming from.
