Nath, the reason I think the Ta-152 would not be unbalancing is like Juzz said, below 20k the 190D9 was a superior aircraft.
Plus almost all Ta-152's, were the H0 (zero) model,
not the H1. The H0 did not have either MW50 or GM1 boost systems, due too production problems and availability. But otherwise was similar to the H1.
I have some charts of Focke-Wulf's own performance testing and comparison between the D9,D12&13, 152C (only prototypes ever built), and the H0 & H1 models. And of all these planes I would much rather have the D9 than any of the others.
If I remember correctly, of the entire Ta-152 production run (very small in its own right), approximately less than 30 of them were the H1.
Leonid, I finally found a production number on the Yak3's with the Vk107's. Of the Yak3's produced during the war, 100 of them were equipped with the 107.
Yep the Yak3(107) would be a real terror, in fact its one of the few aircraft that I can think of that could compete with a Spit XIV on even terms.
Pyro, I change my mind! This is my pick for uber-postwar-fighter-aircraft!!!

I agree, the two uber planes I want too see the most are this Yak3 variant, and the P-51H
