No, I think by "comment on the delta", he was asking for someone to discuss the differences.
I think the two classes are quite similar in intent and procedure, except that GUE does require the student to be entirely gear-compliant for the Primer, whereas Essentials only requires a long hose and non-split fins.
Sometimes people don't have the equipment for the class, and are renting or borrowing it -- I know I was, for Fundies. I went back to a Cobra computer for some time after the class, because it's what I HAD, and my husband had conniption fits over me giving up a perfectly good computer just because somebody else thought a brass and glass SPG was preferable. To this day, my husband uses his Cobra!
