They're more likely to get "battler of heresy" trait lines in my experience.

They also tend to get the 'growing faith' trait line as well. Having the purifier (aka battler of heresy), missionary and that line are a sure way into the College of Cardinals and to the Papacy.

In addition to better traits, it seems that most of my priests are less likely to get traits that make them unorthodox when they have buddies, so that means less heretics.
