I had FFS with Dr. Ousterhout 6 years ago, and he did a great job on me. I'd had some other procedures done before i'd went to him (I transitioned in the early 90's before FFS was prominent or even around), like 2 nose jobs, Adams apple reduction, breast augmentation, and ears pinned (sorry, just using layman's terms for the surgeries). With Dr. O, he did my forehead (I had the type 2 forehead procedure, although I think he changed the name/classification), orbital rims reduced, jaw and chin reduction, and that's it. I probably should've had a lip lift (he suggested it actually), but at the time I didn't have enough money for it.
Everything was very smooth. Dr. O and his office were very, very nice (I especially loved the office manager; not Mira, but I think her name was Tatiana? or something like that, think she was eastern-European), and the surgery and after-care was fantastic (I stayed at Cocoon House after, and omg those girls are just incredible). But even though they tell you it can take awhile for swelling to go down and to achieve your final results, i'm not kidding when I say it took me almost a full 5 years before my chin settled into it's final shape.
Good luck with whoever you choose! I don't regret having Dr. Ousterhout doing my FFS; on the contrary, it gave me incredible confidence and absolutely love my results.
