Can you post images of your face? Just blur out the eyes etc.
Based on the cephs, I like the first better as it keeps your natural facial height. I'm not a huge fan of CCW rotation on underbite cases. I can't tell how far forward they're moving the maxilla in the first plan. It looks like ~2mm.
Gunson is of course very good at this surgery, so going with him might reduce risks...who is the first surgeon? If they're reputable, I'd probably go with that plan. I'd also probably go get a few more consults and bring both of these to those consults.
