Just been thinking about mats tonight, and really I think I have them all, including the new NeoAir. The Exped is the most comfortable and I've used it extensively without fail (can't say the same for three Big Agnes' that are flat in my basement). I took the Exped to Alaska goat hunting last year and had to add air about every other day, but it never went flat. I still have a nagging feeling about taking an inflatable on a "big" trip as anyone can fail.....I will carry an extra-large section of closed cell foam for a sit pad that can do double duty in case of a leak.
