Unless you're price-sensitive and want to avoid the NFC for tat reason, I don't see how the NFC version is worse. If you don't want NFC at all, a bit of foil or even wire should physically block it.

It is possible to disable the NFC function, if that would be satisfactory?

Referring to the yubikey merger with a SPAC company called ACQ.

Before this ACQ Bure deal, in case quality, features, trustworthiness, or pricing change.

Okay, but the YK5 was available before this acquisition and is still the same key after. Not sure how the NFC part factors into your assessment. I assumed SPAC meant something technical about the key.
