I officially "unthank" any posts on this thread that seek to direct attention solely to contrasts between AA or 12-step programs and any other program. Including any of my own posts if they can be construed as doing that.
My initial suggestion was a contrast between programs that cost money, particularly expensive programs, and free ones. Particularly I was interested in inpatient vs. free peer-support. I heartily do not endorse the direction some posters have taken this thread.
