No feature is perfect. This still protects against data theft or prying eyes if you lose your phone, my primary concern.
Those finger-swipe locks that people seem to be so fond of on my University campus are less secure than decent facial recognition software IMO. Hypothetically I could find a phone left behind in the library and see their passcode pretty clearly in their finger smudges on the screen. Do you remember to wipe your screen clean every time?
Facial recognition will not deter someone who is deliberately targeting you, no. Maybe some combination of facial recognition AND numeric-passcode would be more suitable.
