It’s very possible that Face ID is bad, but not all authentication is created equally.
The only reason you list as to “opt out of biometric authentication” is that the facial recognition on your 8 year old lenovo and the finger recognition on hp laptops did not meet your usability requirements.
Face ID will make use of a lot more hardware and software resources than Lenovo’s old laptop did. Also, just because a company includes a feature on their product does not mean a feature is implemented to your liking. Lenovo probably did not intend for that feature to secure your data in all scenarios.
