Depends on how you define "random" thief. Random as in someone taken randomly from anywhere on earth? Yeah, faceId is likely more secure. Is it random as in someone taken randomly from your city or country (which is the most likely scenario)? Then we're talking someone who is likely significantly closer genetically and in appearance to you, which greatly increases the odds of the thief being able to unlock the phone. In more isolated places like islands this effect is even more pronounced. On the other hand, fingerprints don't suffer from that effect, as they're unaffected by genetic diversity.
