The Ju-88? Goodness me, that couldn't do half what the Heavies could do.
I would say maybe the Ju-88 vs. the B-25 or possibly the B-26 as Lucky stated.
You will find the Ju-88 and the B-25 matched up well against each other, with the Ju being a bit faster, and the B-25 having a bit more range and combat load.
Of course the both American planes had better armour and defensive weapons, and what most considered better engines (especially if the Ju-88 was using the older 801's versus the Jumo 213's).
