When we started skin-diving a year ago my wife went purge for the percieved ease. I went non-purge to avoid a failure point. Nobody is going to tell me that embeding a hard object in a silicone membrane that will get frequently pinched is not a failure point, let alone the potential for the valve to hang or have a grain of something hold it partly open. This is my logic I you think otherwise so be it.
When we began OW instruction our instructor pointed out her purge as a potential failure point It wasn't a replace it or you will die thing just a comment, there is of cource the intructor/student effect. He believes it enough that he does not stock any purge masks. I couldn't disagree and told her to go go non purge if she would be more comfortable and she did. The other is still OK for skin-diving and as a spare so it's not entirely like she threw it away.
Now that she's comfortable clearing she says it's like rolling off a log and dosen't miss the valve a bit. She put her old purge mask on the other night as we were stowing gear and tried to do a valsalva and commented that it was PITA.
That's our experience, YMMV.
