I'm not really sure how to answer your question. I feel like there are many MGB people. The sleeve seems to be the most popular right now but everyone has their reasons. We all have reasons for choosing what we did. I chose MGB for the malabsorption and (possible) dumping.. some people choose other options because they don't want those things. It's just a preference.
I'm really glad you're having great results and an easy time. I'm happy with my choice as well but I do have very occasional reflux (which is AWFUL), heartburn from time to time and plenty of frustrating moments. They can all have their downfalls. At the end of the day, if you follow your plan it doesn't really matter what you choose as long as you get where you want to be.
