How do I choose which surgery to have?

My doctor has recommended the lap band surgery for me. I am 5'8" and weigh about 280 lbs., so i have about 130 lbs. to lose. I am wanting to have a safe surgery but I want something that is going to be successful. Does the RNY surgery seem better? How do you choose?
