Long pins and passwords make you a lot more susceptible to casual attackers, as they can be gotten from shoulder surfing and casual video, like e.g. surveillance footage.
Fingerprint replicas (or your actual fingers) are obtainable by targeted attackers of some sophistication. But if you're targeted by attackers willing to go that length for you, you have other problems. IMO, fingerprints provide the best practical security.
