I had the sanctuary last year, but my feet and hands would get too cold to bowhunt way before hitting the temps it was designed for, and I was mostly hiking into public with sticks and a platform. Sold it and got the woodbury, which I have been using this season. With the right layering, it has been usable from windy, damp, mid 20's up to the 40's. I bought a Sitka hand muff and boot blankets for rifle season, and might reconsider the sanctuary, since the woodbury, even with a few layers under it, was a bit chilly for me, and I am hunting private with fixed stands and blinds more. I also just got a LPP a few weeks ago and it is super warm, usually just a light layer when I walk my dogs in the morning.
The one thing that I will mention beyond the temp ratings, is the FirstLite jackets are way more stand/blind hunting friendly, vs the LPP. The articulated sleeves, two way zipper, and esp the pocket layouts make it nice to have. Things like a mesh kidney pocket for a hand warmer show the thought put into the design.
