If you look at the PQIA test on synthetic 5w-30 oils, there appears to be some significant differences in the additive packs. M1 is clearly a better oil based on TBN, VI, and NOACK %, but MSS is a solid product for the price.

They don't seem all that different though, only in the D5293 Viscosity @-30° C mPa, Calcium (Ca), ppm, Magnesium, (Mg), ppm, and Boron (B), ppm areas are there significant differences.
I imagine the Super Syn would hold up just fine for my 5,000 mile OCIs and it would also provide a roughly $20 cost savings, more than paying for the M1 oil filter at $12.99.
You can look up the MSDS too and see that MSS is pretty much all a group III oil where as M1 always has some group IV (the amount varies for viscosity and type).
But for 5k OCI's, MSS is easily up to the task. I've run it on 8-9k with past vehicles and it seem to do just fine.
