I have a big agnes air core sl, a thermal rest neo air camper, and a thermal rest neo air xlite
Recommendations kind of depend on what you want.
If you want comfort and bullet proof reliability, the neo air camper is it.
Its made of thermarests most durable material. Its also their highest comfort rated pad.

It also comes in a 30 inch width. Most backpacking pads are 20 and 25 inch widths.
Downside, not size, not comfort. But it is heavy. Well, lets get serious. its not that heavy. But if you are a ounce counting gram pinching backpacker, its considered heavy.
It actually only weighs 24 ounces.
Now thats a lot compared to an Xlite.
12.2 ounces. So, its double. But the Xlite is not rectangular, not as thick, and not as durable.
The big agnes air core sl is ok. Its my least favorite pad of the three.
the pad reviews on outdoor gear lab are the best I have found.
Unbiased, fair, accurate.
I find that I like the neo air camper 90% of the time. When going far and light, I like the xlite.
I want to try one of the klymit body map pads, but just have not had the nuts to pull the trigger and buy it.
they look neat. super light. But I just get freaked out by all the gaps.
