This can be a difficult number to rely on, as some products like a down-filled jacket Are designed to retain heat, so the more fill power the better.
On the other hand, in the case of pillows, while more filling power means more fluffiness, it can also mean that more heat will be trapped, leading to a never-ending search for the cool side of the pillow. In some cases, you'll find that pillow manufacturers have stopped including fill numbers in their descriptions, specifically to avoid this confusion.
