False equivelance is his way of obfuscating the issue: He was making up his own totally arbitrary comparisons and saying every Ju-88 needed an exact counterpart Mossie, and vice versa. A false comparison to try to lobby for something -- when no such equivelant was needed. Further, the Ju-88, while quite versatile, was very limited in big-gun setups. Most proved dangerous to the plane itself, and none were very widespread.
Much like several other airframes in the war, the Ju-88 was a testbed for nearly any and every weapon in the war. That doesn't mean they were successful or even serialized.
P.S. Many/most of the corrections added to the Me210 were already in place by at least end of 1941. Depending on how you lobby it, a lesser-powered version of the 410 was already flying in what we would call "Early War".
