It looks like the engine may still be breaking in... Or... if there is more than 5000 miles on this engine, I would have to surmise (us un-educamated dunderheads here can only surmise)
that neither of these oils is protecting the engine all that well.
I'm somewhat inclined to go along with sunruh's idea about the 50 weight. Both of your oils have sheared to "P"-water... very light 30's from the numbers you provide.
This engine is definitely thrasing the oils. Here's my theory:
From a serious perusing of the UOA's here and elsewhere over the last year it has become obvious to me that synthetics do not reduce wear--and in many cases seem to show accelerated wear. This seems to be the case with various syns versus various dino oils in various engines read by various labs--so it isn't an isolated or individualized issue.
There's a "murmur" beginning to be heard that has this idea that some synthetic bases actually have a "blocking effect" on the ZDDP, keeping it from adhering to the metals like it's supposed to do. There is an article posted here at BITOG somewhere regarding this issue. Some Canadian university did the study.
So anyway, if the above has any validitiy to it, that would mean that elements of the base package in the synthetic oil are "substituting" for the ZDDP anti-wear package. This might explain how these purportedly "shear resistant" oils shear so much.
I'm of the opinion that a petroleum 15W40 HDEO such as Shell Rotella, Mobil Delvac, or Chevron Delo would turn you in a better UOA than these syns have done. These HDEO's have a robust additive package, and the base oils won't crowd out the ZDDP on certain surfaces. Aluminum is supposedly very susceptible to this effect, and I note that your AL numbers seem pretty high. (That said, I don't know the Universal Averages).
Admittedly, the above is only a theory--but it's backed up by the evidence in the UOA's here and elsewhere, I would argue.
One thing I learned a long time ago about theorizing: The model must fit reality. The reality is that your wear numbers could be better. The reality is that neither of these oils has done much to mitigate the wear, and both have sheared considerably for some reason.
Try some Shell Rotella 15W40. It's got no moly at all, so no clutch issues. It's got lots of ZDDP, and certainly wouldn't shear any worse than the syns here have. I'll bet that it'll protect better and shear less...
