I switched to my first Fingerprint phone a year ago, and I can't imagine going back to passcode unlocking for convenience reasons. Which is the most secure? It depends on the threat model. With an NFC sensor, I suppose it should be possible to unlock a phone from a physical key, but is it really convenient? The only downside of a fingerprint is that there is no key rotating. If your fingerprint pattern is compromised, you are screwed. This doesn't have to be a security vuln in the device itself. A determined attacker can take your fingerprints off the screen surface or back fit eh phone.
