If it's going to be single-factor authentication, more complex passwords are more difficult to circumvent than biometric passcodes.
Biometric passcode locks are not all that difficult to circumvent, even as it would tend to localize the password circumvention at first. For example, there are people who have used their sleeping/hung-over roommates' fingers to access the data of phones that get unlocked by a fingerprint. And there have been examples of people using photos -- even of fingerprints -- to access devices locked with biometric passcode.
