I've used my Contrail quite a bit; I've now switched so that my go-to tent is a Lightheart Designs solo, but I sort of "kicked the tires" on the Moment before I bought it.

Still, I don't have enough experience with the Moment to really compare them. I like the Contrail just fine. I think the Moment would handle wind better, though with intelligent site selection that Contrail is okay. For the weight, the Contrail is plenty roomy inside; I find that I have to sort of scoot my butt towards the door to sit up comfortably in it, but that's not a huge big deal.
