Someone correct me if I'm wrong, but I think the 4.1 R value is somewhat "optimistic", so the difference may not be huge. If/when I get a neo air I'll just add a GG thinlite pad (about 1.5 oz?) to it when I expect cold temperatures.
The other advantages of the neo (apart from weight) are that the 'baffles' are horizontal and there are plenty of them… so it should feel flatter to lie on and won't wobble so much. Plus it is rectangular which gives you a little extra room before your legs start slipping off the pad.
