I think I read your OP wrong.
I thought you were asking which is better, a trained counsellor who has never experienced the trauma, or an ordinary person who has experienced trauma.
I read it that way as I have known of people getting advice from people who have experienced stuff and giving their tuppence worth. Which of course may not be great advice in the end.
Good question though.
