Not "screwing the thread" for your questions, just how do you correlate viscosity index and flow ?
These the two PDS ???

You can plug them into the Widman charting tool

Clearly, so close as to be indifferentiable in terms of viscosity and typical versus actual specs...and as to difference in "flow", in an operating engine...ummm, that was actually YOUR statement, which I asked you to justify.
Between 40C, 100C, and past 100C, the lower viscosity index oil will (according to your premise) "flow" more, clearly.
Back to your questions about the other advantages of the MC 5W-20, as per the data sheets.
It's got a massive flashpoint of 206C, versus the Pennz regular of only...ermm wait, 229C.
Well there's the CCS...hmm, that's the same.
Pour point ? well one is -42, one is < -42.
But yes, one has higher viscosity index
