What is the main difference between Suboxone and Methadone?

From my research it seems that Suboxone is safer, fits into your life better (no standing in line at 5am) and does not have the severe withdrawals that methadone users experience. I would like some real life answers..it is to get off of the roller coaster of pain pill addiction. How expensive is Suboxone w/o insurance?
