I've never used a Down sleeping bag before but I needed something lightweight and compacts small. I decided on the BA Anvil Horn 15˚ do to the price and weight. I use a small compression sack and it compresses super small. Used it at 1200ft with below freezing temps with a mummy bag liner and cheated with a hot tent. The sleeping bag was super comfy and matched with a BA pad. I was able to attach the bag to the pad "no more sliding of the pad total game changer". Hard to say how it performs in cold temps but when the stove went out I was able to still stay warm. I'm happy with my purchase.
