You have to go with what you're comfortable with. If retaining sensation is a top priority, you might prefer one procedure over another. But do carefully weigh your priorities.
At my age, I was less worried about aesthetics and more worried about function (nipple sensation), convenience (wanted my surgeon to be local for a few reasons), and expediency (needed an appointment AND recovery period that didn't conflict with my academic work schedule). So I went with a less experienced surgeon an hour away who practiced the pedicle technique and had an opening at exactly the right time. My chest looks fine when I wear a shirt, and I don't go about shirtless in public except in my own back yard. I have the physical sensation that I wanted to retain. And I saved a good bit of money and escaped some stress by doing the surgery locally.
My decision wouldn't satisfy everyone, but it was my choice, and I am happy with it. I wish my chest looked a little better, but I knew up front what I was getting into, and I would do it again the same way. So I guess following my own heart and not other people's advice worked out for me.
