It's all relative. To me, RnYers can eat SO MUCH! They talk about their 1-1.5 cups of food and my eyes boggle.
I did run into someone on a non-WLS forum who kept going on and on about RnY and how it _______. But everything he said about it was actually something that can (but doesn't always) happen with a DS. It was weird. I think he had a band and wasn't willing to say so in that forum and felt threatened by my saying the band isn't this safe surgery that is non-invasive compared to the big, bad, dangerous RNY, but that all the WLS are pretty safe and they are all invasive.
My experience is that most people don't even get there is DS (or sleeve) so they don't have an attitude about it because they never heard of it.
