I think this has to do with a lot of pads no brands in particular when it comes to inflatables. I noticed the comfortability was much better after sleeping on a pad not inflated like a pool toy.Not that it applies to folks on this thread, but I’ve always noticed people way over inflate their pads like it’s a pool toy and then wonder why they have issues with it. I sleep on my side and only put in enough air so that my hips do not hit the ground. It seems under inflated to other people. Just .02c
For 2020, most companies, and any company being sold at REI is abiding by ASTM standards for r-value testing. So any 2020 production mat will be much more apples to apples when you compare r-values.The only downside to thermarest in my experience is the price. As I've reminded folks elsewhere, R-value is not standardized, so companies make up whatever they want. Thermarest is definitely the warmest of them all.
I'd go for a NeoAir if you're looking to shed weight. Just make sure you clear sharp things out from under the tent. Have the xtherm version and it's been super durable, but it's a bit higher denier
