I chose VFS. I was at a consultation for FFS in fall and basically they said there is no essential need for FFS - I felt more or less the same. So it is more optional, something I want to do maybe - or maybe I dont need it. Its a big surgery and more costly. And I was more annoyed by my voice, which was for years an issue with people asking me about it or misgendering me because of it, so my choice was individual. I guess one has to honestly assess what is bugging oneself the most and maybe which part is mostly messing with the perception of others and then go for that. If your voice is mediocre, but the face has male features, FFS is better, if the face is somewhat allright but whenever you open the mouth people look shocked or nervous, then VFS may be better.
