Regarding the Neoair, I just don't like how it feels. Could be the horizontal baffles, probably that. Some people might like this more because it can flex to the shape of one's body better, but for whatever reason, it doesn't work for me. In contrast, one of the things I like most about the Peak AC is the way there is a "groove" between the baffles, and the outside baffles are larger. I find it really comfy for both of those reasons and it seems to cradle me in place a little more than my other pads. You're welcome to borrow both to try out.
