What is the ultimate winter puffy jacket?

The answer is: I'm not entirely sure - however, here are some of the most highly rated ones.  I am rather fond of Patagonia myself and would likely go in that direction...
Also, the name is... everything.

Patagonia Women's "Down with It" Parka $279
40" length, removable hood, slim fit



L.L. Bean Ultrawarm Coat $189
The name sort of says it all.  And let's be honest - Mainers
do know their winter coats- comfort rated to -50 degrees.

Land's End Stadium Squall Coat $159
This coat was inspired by watching football outdoors in Wisconsin winter, so yeah.  Rated to -30 degrees.

Patagonia Women's Downtown Loft Parka $349
"with the 800 down fill it is ultra warm when walking through the frigid streets of new york city! I cant believe I waited this long to get this coat. All the years of freezing from the waist down are over! I highly recommend it!"
