(I cant seem to find a spec sheet for the ESP 5W30 that shows the KV at 40C).
in terms of really cold starts, MRV is not going to trump KV until you get below 0F (personally, I will never see those temps).
Although my location isn't crazy in terms of cold, there will always be some days each winter where the temp will go below 0F. Even this past mild winter we did see -4 F. Actually I was more thinking about compare and contrast for summer driving. And that's when I noticed that the KV at 100 C was more for the 0W30 than the 5W30 (albeit not much it 12 vs 11.8)

This isn't made anymore. I think now it is just called ESP.
