As one of the 262 pilots I can say: We weren't a real threat. We were a tool to be used, but a limited tool. Allies had such overwhelming air superiority I saw at least 30+ bombers in 2 large waves going past me, and I was the only person in the sky at the time. While constant allied P51s dove on me none were a real threat. It was the lazer guided AAA of a triple-ack-platform (a full formation) that shot out my oil, not the work of the escorts.
262s aren't much of a threat at all. Least of all to the way bombers are modeled in this game.
