I don't have any experience with the Tensor Trail, but just looking at the R value vs weight and cost, idk that I would even consider it. I do own the Tensor All Season (in a reg/wide) and a Xlite NXT (in a Reg mummy), I've also slept on the Xlite NXT in a Reg/Wide.
I'm also a warm sleeper but I use a quilt. I also tend to move around a lot when I sleep and do end upside sleeping a good bit, but I don't have any issues sleeping typically. My use is mostly earlier seasons, but I do have time on them in sub-freezing hunts.
IMO the All Season is more comfortable and has a better valve design, but it comes with a weight penalty (~6oz) especially compared to my Reg/mummy Xlite. It is not noticeably warmer to me despite the higher R value, but I do prefer the face material feeling against the skin slightly. I haven't had any durability issues with mine as of yet, but to be fair I don't feel like I have enough nights on it to really weigh in on that.
On the flip side I had an original Xlite for years and it is a bombproof pad, plenty warm and probably the lightest option that most would recommend, in any configuration, but it was loud and the original valve was terrible. Enter the NXT and they updated to help with noise, upgraded the valve and somehow managed to make it thicker and warmer without adding any weight. The NXT is definitely comfortable enough for me, even in the mummy configuration but I will admit I wish I had the wide.
All of that to say; I think if you're trying to count ounces and want a tried and true pad that is plenty warm for most all backpack hunting scenarios the Xlite is hard to beat. But if you were willing to sacrifice a few ounces of weight for a little bit of comfort/convenience, the All Season seems to be a solid choice also.
