To be fair, they're more secure in the average case where someone leaves their phone on the bus and someone else picks it up. Joe Shmo the phone thief isn't likely to know how to lift fingerprints (e.g. off the phone itself), but they can unlock an unsecured phone. If that's the difference we're talking about, fingerprint security is way better than no security and has about the same convenience. I don't use the fingerprint sensor on my phone because I prefer better security through a relatively long password. However, I'd much prefer that someone use something than nothing. I think patterns are a reasonable alternative, as are PINs.
