BA Air Core and Insulated Air Core, depending on the temp. I like the vertical baffling better than the horizontal of the NeoAir. If cost were no object to me, I'd probably be talking about my Expeds, but the Big Agnes pads are quiet, comfy, and inexpensive, and I have no complaints.
If you're not accustomed to air mattresses(I wasn't) just remember to partially deflate the mat 'til it's comfortable after you climb on. May take a little trial and error to find your sweet spot at first, and blowing a mat back up some if you let a little too much air out.
