This is what convinced me....
the risk associated with both surgery are equal, and the risk of complications after are equal.... BUT... if your sleeve leaks, it’s worse than a bypass leaking. Here’s why.... the sleeve leaves the esophagus and intestines attached... but your system is built for a certain sized stomach. When they make the stomach smaller, it creates a high-pressure environment. This is why food and bile pushes up. If you leak with this high pressure environment, the consequences are more severe. With the bypass, it is a low pressure system. Everything needs to be adjusted for slow system. (The speed in which you eat and drink also needs to slow down - or you get dumping).
The risk of leaving after a sleeve was my deciding factor and my surgeon said it was best for me.
Good of luck with everything!
