my 2 cents not counting inflation.
selecting a srs surgeon is a pretty personal choice and while the focus might be aesthetics or if the getup works sexually the truth(tm) is most western surgeons these days use a similar technique (inversion with scrotal primary graft) and leave the details to how they were taught things (peri skin and urethra tissue use).
if you are going to pay cash for it vs some sort of coverage by a 3rd party (insurance) can either expand possibilities or limit them.
Aftercare doesn't stop when you are discharged from the surgical center or hospital. is your GP/obgyn/whatever able to perform care needed be it suture removal or granulation tissue mediation? What if you have to have the foley (urinary catheter) reinserted for a couple days?
Do you trust the surgeon? even the best ones have cases where complications happen (patients bleeding out, aesthetic issues, severed nerves causing numbness, etc). Sometimes they can repair a complication, sometimes they can't. to use a phrase from financial companies: "past results are not an indication of future returns". Just because one person got a good result doesn't mean the next person will. Most US/Canadian srs surgeons are pretty ok at what they do least they get sued into oblivion. The real work is figuring the rate of complications any given one has and if the risk (as all surgery has) that one is willing to take.
