It's only 'more secure' in the sense that it's more difficult to
decrypt/break a key than it is to decrypt/break a password.

IMHO there are situations where it is decidedly *less* secure to use
public key authentication.  I access my home machine from two or three
laptops using ssh.  If I use public key authentication from those
laptops then if I lose the laptop the keys are vulnerable to an
attacker.  If I use password authentication then someone who has my
laptop has no more information than they would have if trying to break
into my systems from anywhere else.

Horses for courses.
