ALT is an option if you're skinnier- I think sensation is almost as good as RFF. But it isn't an option for people with larger thighs. I don't know TONS about it specifically because I'm not a candidate.
As someone with larger thighs, I'm personally looking at abdominal, but specifically from Dr. Christopher Nim at the London Team because they can do a nerve hookup about 50% of the time with the flap they take for the urethra. Sexual sensation isn't AS important with me and the scarring for this is usually hidden under the underwear.
I've also looked at MLD, but personally decided against it because I heard it can sometimes stretch top surgery results. That one I think is just under RFF and ALT in terms of sensation.
Dr. Ting's new procedure isn't really defined for sure yet and to my understanding he doesn't believe nerve hookups work and doesn't do them, so if sexual sensation is important, that's a big consideration with his procedure. He's not been extremely forthcoming with info but it's been great for the people who have gotten it to my knowledge. I think it results in the least scarring that I know of.
