My opinion: the VSG is a great surgery IF you know restriction is all you need. I think the long-term results will be better than those for the band, and it has a lower complication rate than the band since there is no foreign object to erode, slip, etc.
I have a VSG stomach but with a little intestinal malabsorption (went in for a DS, came out with a semi-DS). I have spoken with multiple VSG patients, and many of them are doing very well. Some do not lose as much as they would have hoped, but some sail right down to their goal (but this is the case with pretty much any WLS procedure).
If your choices are band or VSG, I would vote for VSG. Mine has done well for me so far - I am down about 45 pounds in less than 3 months (I'm a bit of a slow loser - they say diabetics tend to lose slower, and I am certainly proving that to be true). Plus, if you're a self-pay patient, you won't have to pay for fills/unfills like you would with the band.
