Western Mountaineering and Feathered Friends sit at the very top of the down-bag market, both sewn in the United States with continuous-baffle construction and premium goose down. Western Mountaineering fields the broader lineup here, a deep run of mummy bags that covers summer warmth down to hard winter. Feathered Friends keeps a tighter range but stretches it with a few quilts alongside its bags, and it reaches for higher fill power, which is where the two begin to separate.
The numbers show it. Feathered Friends averages a warmer comfort rating across its lineup and a higher average fill power, into the 900s where Western Mountaineering centers on 850, so its bags reach their warmth with a little less down by weight. Average weights land about even, and both price at a premium within a few dollars of each other on average. What you are really choosing between is Feathered Friends' higher-loft, warmth-forward bags and Western Mountaineering's wider selection and long-proven consistency.
How to choose: pick Feathered Friends if you want the highest fill power and warmth-forward ratings, or a maker that will overfill and tune a bag to order. Pick Western Mountaineering if you want the widest choice of temperature ratings and a brand known for building the same excellent bag year after year. Either way you are buying a bag that, cared for, outlasts most of your other gear. Re-rank the specific models on the full bag comparison to match the temperatures you actually sleep in.
On average, Feathered Friends. Its lineup carries warmer comfort ratings and higher fill power, so its bags reach a given temperature with a bit less weight. Both brands make true winter bags, though, so match the specific model’s rating to your coldest expected night rather than the badge.
Feathered Friends, on average. It builds many bags around 900-plus fill down, while Western Mountaineering centers on 850-plus. Higher fill power lofts more warmth per gram, which is part of why Feathered Friends runs warmer for the weight. Western Mountaineering’s 850 down is still premium and exceptionally consistent.

For buyers who keep gear for years, often yes. Both are hand-built in the United States with continuous baffles and top-grade down, and both hold their loft for a decade or more when stored uncompressed, so the cost per season is far lower than the sticker suggests. Budget buyers will still do better with mainstream down or synthetic.
