First off, there is no magic surgery for weightloss. I did have the RNY by my choice. However, the sleeve has been very successful for those that has used it! You have to feel comfortable with your choice! With any of the surgeries they will require you to use them as your tool. You will have to watch what you eat and get excersizes. Some may cause more malnutrition or and other things may need more monitoring. They all can help you, if YOU use the one you choose correctly, and EXCERSIZE. Monitoring what you eat, and also be working with regards to your mental health to. Mentally and physically you will or may go through things in your journey. Facing them as you go and making changes will help. This will look different for everyone. As so will the weightloss results. We are all made and created differently. The surgeons can give you examples or ideas of surgeries they have seen more successful and ones they preferre. More geared usually to you and your body type, especially with your current medical conditions (if any?).
Surgery is not a magic pill that will shed your weight it will still require in many more ways work on your part for life! Do not let a doctors stats on percentage of weight you may lose determine your surgery. Sometimes insurances only cover certain ones, sometimes it is issues with gerd or other medical issues you currently have, but talk with doctors regarding your individual self. Sometimes doctors preferre to sleeve someone before possible DS. Go to the forums for each surgery you are considering and see what they have to say. Do your research, like you are probably doing and make your choice. Always remember it is your journey and success of your new tool will be what you make of it! It can be a hard decision to have a surgery done, and the decision of wich one, we all have had to decide. As you may have seen, so many do not regret our decisions! It can be life changing!! For me it has been life changing!! Please keep posting, lurking, and do not give up! Educate yourself, and know you are not alone. Also since you are in the higher BMI, note to yourself, your journey may be longer to goal. It is doable, but will take longer and more willpower and self motivation to get to goal. For long term success, life long it will be work forever!!
