I had my surgery with McGinn earlier this summer. The deciding factors for me were: reputation, insurance coverage, personal comfort (after consultation), and convenience (location and timeline). I didn't consider Brassard because of the insurance issue.
It's hard to tell about longer-term outcomes right now, since it's still so early, but I'm happy with my decision, and would do it again. My initial recovery has been smooth. I'm satisfied with my interactions with the surgeon and her office.
I think that any of the highly-reputable surgeons in the US and Canada, and the two or three in Thailand who seem to be doing excellent work, would be fine choices. This is such a routine, predictable surgery for them these days. All of them would have good days and less good days, and we all heal differently. Not to be blasé about it, but isn't it like that? It's the biggest thing in the world for us, but all in a day's work for them.
For my part, I think it's important to meet the surgeons in advance, if you can, just to make yourself comfortable with your choice and their take on the process. And choose a surgeon/place you can afford with some buffer, that's reasonably easy for a partner/friend/family member to accompany you.
