I'm just the opposite. PCM doesn't solve radio problems it just hides them and the failsafe... well I've seen more plane go in lately from a total lockout than from just jumpy servos.
I will say that PCM does have a shorter freq wave that helps elminate outside noise but I'm not one for the lockout feature. Even if you set it at a slow idle, with neutral controls or even with a little up elevator if you lockout in a knife edge or inverted your still bumming.
Now as for the servo resolution... resolution is the measurement, usually in ms, of the smallest distance the servos arm can move. I don't know how or if PPM/PCM can relate to that but it might.
