Both forecast a colder and snowier winter than usual, but long-range forecasts aren't the only thing in an almanac. You can use a farmer's almanac for planting guides based on the moon, and they're filled with farm-related reference information - everything from the serious, such as the length of gestation for a goat, to the hilarious, such as how to hypnotize a chicken! (That truly could come in handy sometime!)
Both almanacs also feature a variety of articles both humorous and useful, and certainly good reading during the upcoming forecasted-to-be-frigid long winter. Tell me how you use your almanac! Which one is your favorite? What is your favorite part, and what have you found to be most useful?
