TL;DR
Owners overwhelmingly love the Nemo Disco 15 for its roomy spoon shape, which finally lets side and stomach sleepers stretch and roll without the boxed-in mummy-bag feel, and most stay warm and cozy through cold and shoulder-season nights. The main tradeoff is weight and bulk: it's noticeably heavier than ultralight bags, and a few cold sleepers feel it doesn't quite hit its 15-degree rating. It runs warm in summer, so plan on it as a colder-weather bag.
81% of 185 verified owners recommend the NEMO Disco 15, based on real owner verdicts aggregated from Reddit, enthusiast forums, and YouTube.
