I am only 1 week post op but decided on the sleeve after originally picking the RNY Bypass. I wasn't willing to deal with gastric dumping (I want to enjoy a ribeye steak later on, even if it is a small portion), the risk of blockages, and results from malnourishment concerned me long term.
My sister is in the medical field and spoke with a nurse friend of hers who worked in the bariatric center of excellence at her hospital. The nurse was very firm that I should do more research and look into doing the sleeve instead to ensure I was happy with my decision (I had chosen bypass and had my consultation at that time).
I'm 6'3" Male started at 415lbs and a currently at 380lbs. I don't have years of experience to share what it will be like, but I am only a few months ahead of you in this so I think our perspectives are similar.
You will have to examine all factors and determine what is important to you. Concern of regain may push you towards the bypass. I placed other factors in front of that when making my choice.
