I have both, but the Paco is at about 15 years older The foam in the Aire feels firmer, probably because it is so much newer. For some reason though I still prefer my old Paco to sleep on. I just find it more comfortable, and the "tooth paste tube" valve makes it much easier for me to fine tune the amount of air in it than the raft valves on the Aire. Your experience may vary. The Aire is definitely a good value for the cost. I also have an NRS brand pad and it is very similar to the Aire in firmness and construction quality.
