Suporn vs Chettawut technique?

There's lots of posts about this topic already but I wanted to ask about technique specifically.

What are some differences in technique between the Suporn clinic and Chett? I know they're fairly similar but I'm worried I will get a less sensitive clitoris from Chett.

My goal is to save up and get surgery from Chett and maybe a revision if needed from possibly Theerapong, but the Suporn clinic does offer a free revision so that's also worth considering. They end up being similar costs if I end up needing a revision, so I want to compare the technique of Chett and Suporn first before I decide what to do. Thanks for your answers !!
