A total toss up; both are way more capable than the 10k miles you're going to put them through.
Construction is nearly identical; silicone ADBV, wire backed syn media, premium build with robust materials, high holding capacity, etc.
Any UOA data or PC data you could find by using either of these would be well within the "normal" deviation of typical use, and would indicate they are statistically the same. While the lab efficiency ratings (of which Wix has become quite evasive in posting recently) may favor one over the other, the real world use will not reveal any difference; they are both premium products. Any difference would only be attributed to daily variation and not performance potential.
It simply won't matter, except in your head. The engine will not be able to distinguish any difference whatsoever.
Total overkill for your intended OCI, but as BOF would say, that's the U'Mericun way ...

Conventionals vs. Synthetics isn't about which is "better"; it's about which lasts longer, while assuring safe operation, in relation to cost. Any product can be over or under utilized. The same applies to filters.
Make an informed decision; first consider your operating conditions, next determine your maintenance plan, and then pick your lube and filter. Don't do it the other way around ...
