I think one of the differences in weight loss with RNY vs the band is where there is a higher risk for failure.  Most RNY-ers lose alot of weight because like you said they have that honeymoon phase where they can lose even if they cheat.  I think the greatest risk of failure with RNY is in the risk of regaining if the changes in lifestyle haven't been made during that honeymoon phase.  With the band, the first few months are often referred to as bandster hell.  People who don't push through the initial period, follow the rules, and get their fills, will not lose weight to begin with.  Thus, I think the greatest risk of failure with the band is right off the bat when it requires the most dieting.  If people have not educated themselves about this, they often give up before they get a good start.
