The Dora was better, definately, but its hard not to see the Yak-3, Yak-9U and the La-7 as VERY competitive, particularly below 10,000 feet.
Don't write of the hardware that the Soviets flew. The qualitative gap between the 190D-9 and the late war Soviet fighters was far smaller than the qualitative difference between the earlier Yak-1s, Mig-3s and LaGG-3s (not to mention the I-16s and I-153s) and 1941-42 time frame fighters like the 190A4/A5 and the 109F-4/G-2s.
