No, the jerk is pretty easy to understand, if not execute. Clearly to do it efficiently for olympic lifter status it is not easy, but for "field athlete" purposes pretty simple. I still believe the snatch is easier to learn, but again a lot of that comes down to individuals---some can pick up deadlifting by looking at it, others struggle for months to find a groove.
I will say however, I do not trust any high school programs to know what the hell they are doing when teaching the power clean. There are some top coaches out there no doubt, but so many bad ones it makes crossfitters look positively gifted in coaching olympic form, and we all know what the opinion of crossfitters tends to be around here (one I share in terms of technical coaching).
I think they both carryover well but in different manners. However I do side with Christian Thibaudeau that the only high pull that really carries is the snatch grip high pull. Clean high pulls turn into arm pulls.
In general, however, my point is that the olympic lifts can be killer for powerlifters if you use them in their appropriate role for powerlifters. If you do not, you truly do ruin the lifts.
