According to Wiki-Pedia "The aircraft of V./KG 40 (which was redesignated I./Zerstörergeschwader 1 in 1943[11]) were a significant threat to the antisubmarine aircraft and operated as escort fighters for the more vulnerable Focke-Wulf Fw 200 Condor bombers. Between July 1942 and July 1944, the Ju 88s of KG 40 and ZG 1 were credited with 109 confirmed air-to air victories,[12] at a cost of 117 losses.[13] They were finally deployed against the Allied Invasion of Normandy in June 1944, incurring heavy losses for little effect before being disbanded on 5 August 1944.[14]"

It would seem that most of the successes of these long-distance patrol fighters would have been against "Coastal Command" anti-Uboat aircraft. I don't have any data to show their effectiveness against carrier (or CAM) fighters or losses to them. I agree, it would seem that a Hurricane would be at significant advantage against the Ju-88.
