Hey flipper,
I asked my docs at mayo the same question,here"s what they explained,
Sleeve is good for over eaters, who love sweets
RNY is good for folks who like savory tastes like pizza, cheese and spicy foods,
Dswitch is best for sugar lovers and carb-cravers
The RNY is the gold standard, and works well with folks who follow their diet
Dswitch is most extreme, and can cause digestive woes.
I love Nachoes not ice cream so I will be getting RNY on Friday, even tho my first choice was Dswitch.
(Mayo no longer does banding!)
