If I remember correctly, the Bridge at Remagen was the only time German jet bombing missions (Me 262 and Ar 234) were used in a relatively sustained manner against a fixed target, heavily defended by Allied AA and fighter patrols. I don't have my references at hand, but if someone can shed some light on the missions, it might give the best indication as to whether the German jets of the time would have performed effectively.

As an aside, an Ar 234 nuisance raid against a RAF airfield in Belgium in 44/45 caused minor damage to RAF Meteors on the ground and was probably the closest thing to jet-versus-jet combat in WW2.
