I take it that you mean the Fw 190, and that you don't actually mean the old Bf 109E... For a start, it would depend on which version of the German fighters you are considering, and then on which type of conflict - high or low altitude? The Yak-3 was an extremely agile fighter with an excellent performance at low level. It seems to have been highly regarded by its pilots, and would indeed probably have given any other fighter a very hard time - at low level. At high altitude I suspect that the contemporary German fighters would have eaten it. Tony Williams: Military gun and ammunition website and discussion forum
If memory serves the Luftwaffe issued an order to its pilots to avoid dogfighting with the Yak 3 at low-level. Basically, Tony is pretty much on the money (as ever ).
The Russians were lethal at low altitudes, whatever planes they flew. They specialized in low level fighting, far more than the Western air forces.
