I don't think any model or type of therapy is necessarily better than another but what the client and therapist want is important. They've shown that I think, that it's mostly the relationship and how the "pair" work together? That's pretty much what I believe. I had 4-5 therapists before finding the "right" one for me. My T probably tried bits and pieces of several methods/orientations and learned from me what worked best or what I seemed to like best? I think that's how therapy should work. If you want to talk about your past, I think you should be allowed to talk about your past and have a therapist "clever" enough to be able to make that work for you! One of my life proverbs is, "I'm the right size, it's the pants that don't fit!" and I think when you want/go looking for a specific teacher, they'll show up and be what you need; seek and ye shall find :-)
