Two premium three-season air pads, built around different priorities. The XLite NXT is the ultralight warmth-to-weight benchmark, and the Tensor All-Season gives up a few ounces to add more warmth and more cushion.

This comes down to weight against warmth and cushion. The NeoAir XLite NXT is the pad for gram-counting three-season backpackers. It's the lighter and cheaper of the two, with warmth to spare on most trips. The NEMO Tensor All-Season suits people who want true four-season insulation and a thicker, plusher surface, and who don't mind carrying a few extra ounces to get it.
The numbers back that up. The XLite is lighter and cheaper, and its warmth covers the vast majority of three-season nights. The Tensor answers with more warmth, the step from strong three-season into true four-season, and more cushion. Each pad ships with a single extra. The XLite includes a pump sack for easy, dry inflation, and the Tensor a repair kit.
Pick the XLite NXT if low weight and packed size top your list and its three-season warmth covers your coldest nights. It's the lighter, cheaper, benchmark ultralight choice. Pick the Tensor All-Season if you want warmth that carries into shoulder-season cold and a thicker pad to sleep on, and the extra weight and small price difference are worth it to you.
The NEMO Tensor All-Season is the warmer of the two. That extra warmth is the difference between a true four-season pad and a strong three-season one, so the Tensor is the better call for shoulder-season cold.
The Therm-a-Rest NeoAir XLite NXT, lighter than the Tensor All-Season by a few ounces. That saving adds up over long miles, and it's why the XLite has been an ultralight benchmark for years.
The Tensor All-Season is thicker, so it puts a bit more cushion between you and the ground. That's worth considering if you sleep on your side. Otherwise both are wide, stable air pads.
