If you're going to pay for a synthetic oil anyway, then there's no functional reason to buy 5W-20 instead of 0W-20. 0W-20 will be lighter at startup, which can benefit pretty much anybody, and there's no cost difference between it and a synthetic 5W-20.
It becomes less of a no-brainer when someone who uses conventional 5W-20 is considering spending more money for a synthetic 0W-20. Then you'd want to more carefully weigh the pros and cons, looking at climate, change interval, return on investment, and all that.
