Yubikey biometric models mitigate sniffing the unlock PIN from the computer since it is fingerprint unlock.  

Current yubikey biometric models are FIDO2 only, multi-protocol (FIDO2, PKCS#12, etc) biometric models are “coming soon” 

 Yup, agreed, they should be safe from sniffing.

Might have a problem with being compelled to use it, depending on your country & threat model.

I like the randomized pin pad on the Trezor. That's ideal in my book.
