scroll down to see various histories of Muay Thai versus many styles
some good info , but basically it seems to me to be modified Muay Thai with more throws and no thai style knee clinching which was actually added during the modern history of muay thai once it moved into the western style rules (Gloves, etc) from about the 1950's onward.
In my opinion the strikes are essentially Muay Thai with a few exceptions (Cung's scissor kick being the most notable) and as usual its going to depend on the rules that are being fought and the rules you have competed under plus the usual who brought what to the ring that day.
