Well, for a "bomber" it did pretty well. The only like number, on like number fight I have read was a squadron of Mosquito FB.Mk VIs that encountered a squadron of Fw190As on the way back from a strike. The Fw190s came down on them and the end score was 6 Mossies lost for three Fw190s lost. A good trade for the Germans, but hardly the results bombers with no turrets would obtain. Much more like the results that heavy fighters vs single engined fighters produced throughout the war, no?
Mosquitos were hardly the Fairy Battles you make them out to be.
