I went to Brassard. I'm happy to answer any questions you have. There's a longer review of him buried in my posts somewhere, but the summary is that the looks are good enough that I had a gynecologist mistake me for a cis woman, I am self-lubricating and orgasmic, and depth is adequate. I'm absolutely satisfied with my result. In addition, the aftercare facility was amazing, with nurses on duty 24/7 and regular visits from the doctor himself (or his partner Dr. Belanger). In general, Brassard is noted for being extraordinarily consistent in his results and giving a vulva with a "tidy" look, as well as preferring to stop at 5-6" of depth so as to use the remainder of the tissue for better aesthetics.
Both are excellent, reliable surgeons, and so it comes down to a choice of location and "style" details of the outcome. Suporn, as I understand it, favors much larger inner labia (but the outer labia don't "come together" as well in any pictures I've seen) and greater depth as compared to Brassard, so to some degree it depends on what you want your personal results to look/act like. As for myself, I favored function and looks and then depth was a distant third, and I like the smaller inner labia but better-defined outer labia that Brassard generally creates, so I was thrilled with what I got.
(My surgery also lasted a bit under 2.5 hours and did not require general anesthesia, both of which make it safer than the alternatives. He works that quickly because it isn't, technically, just him - he does the fine detail work, but Belanger handles a lot of the rest.)
