if I were you, I will go for Assayag for one main reason
Both are considered top-notch surgeons, so any of them is a good option at the end of the procedure, but in my own experience, I was not a patient of any of them, but due to my poor bone formation, I contacted both of them for medical advice, Dr. Paley apologized for giving me any advice since I was not his patient, and sure that's his right, but if he did advised me he could help to avoid complication and could do so if he wanted especially I contacted him in the early stage, and two months later I connected dr Assayag and he was very kind and helpful, I wished I did contact him early of my complications.
So I will vote for Assayag, and I'm sure that You will get direct follow-up from him, and you will be sure that he is the one who will cut your leg not someone else ( under the name of paley ) . Plus, Dr. Assayag is very skiLL Forumulll, and if Dr. Paley is more expert has nothing to do with being more expert if both are skiLL Forumulll, it is enough, after being capable and skiLL Forumul is just a matter of a number of cases , and age of doctor
NOTE, Paley is one of the most experts in LL Doctor, and this post is just to show why do I prefer Dr. Assayag
