The compact is less bulky than the extreme and weights a bit less. The compact is good till 45 degrees or so (depends on your cold tolerence). The extreme is good of 32 degrees. I get cold easy, so I liked to extreme. They both do a great job. The compact seems to be more verstile for the season, but in the end, it is up to you to decide on what your level of cold and comfort are.
