I looked into both. I "only" had 107 pounds to my goal, though, and felt the sleeve could get me there without the malabsorption. I wanted restriction without the dangers of malabsorption. In addition, I'm a military spouse and we've spent most of the last seven years overseas. Getting regular blood panels could be tricky, especially in remote locations like our current assignment. And having a surgery that requires me to have them could keep us trapped in the states, essentially limiting my husband's career.
For me, the added stresses and possible complications didn't seem worthwhile. However, if there is a more significant amount of weight to lose and access to high quality, regular medical care, I think the DS is a good option.
I see no reason not to do the sleeve, and if necessary, continue on with DS at a later date. The way a DSer and sleever eat is totally different, though. I know this isn't nice, but I've always kind of thought of the DS as the "lazy" way...how hypocritical is that? Check out ObesityHelp's board on DS. They eat all of the junk we avoid. I feel like it's not guaranteed, but that coming out on the other side of a sleeve leaves you with a more rounded, healthier relationship with food.
I'm biased and freely admit it. I didn't want a surgery where it would be perfectly okay to eat bacon cheeseburgers sans bun for the rest of my life. I wanted to be healthier while still eating like a regular person.
Best of luck whatever you decide,
