Plenty of corner cases which collectively add up to a majority of cases.
Pandemic: you don't want to get too close to the checkout, so you can do it from a six foot distance.
Retail locations with limited space: all you need is a flat wall to put a QR code on, and you can put it up in multiple areas. You could even put it on the floor or hang it from the ceiling.
Forced serialization: multiple people can scan a QR code simultaneously, while the NFC nearness requirement means that only one person can tap at once.
Restaurant table: put a QR code on the menu, scan.
Websites on your desktop or laptop: can't tap, but can scan as usual
That's all just talking about payer UX, not even considering seller UX. QR codes are cheaper and more flexible than NFC.
And, most of all, the fact that QR codes work in such a wide range of scenarios enables the biggest advantage: ubiquity. When they're ubiquitous, they become a single payment interface that you can assume will be available no matter where you go, which is game changing.
