Prog 4/4 on Boeing for Headwind/tailwind.
Winds at touchdown is what matters.
Big tailwind(Y) at X feet is grounds for a go-around. That's what the fourth stripe is for.
Windshear, unstablized, etc, etc.
It's been my experience that the Boeing wind readout is more accurate than the Airbus wind readout. Granted Airbus were 1990's models but Boeing winds were accurate back then while the Airbus wind readout wasn't nearly as reliable.
