Actually (in 2024) for me : 1- Niyomtrong "Knockout CP Freshmart" tje only world champion who is thai, and the most longest reign of all world champions actually. 2- Tasana Salapat "Petch CP Freshmart", he caused a lot of problems for Takuma Inoue. I think currently he has reached a good level to be a powerful challenger.He knows how to vary his shots and he has great power. 3- Wisaksil Wangek "Srikaset Sor Rungvisai" thai boxing star and former WBC Super Flyweight champion. But these last fights are worrying, however he still has some good counter-attacks. 4- Panya Pradabsri former WBC Minimumweigt champion, he has two controversial victories against Chayaphon Moonsri, but remains a great boxer among the division. He has a very good defense, a very great blocker and above all he has a very high volume of shots. 5- I will say Thanongsak Simsri "Black Wolf or KO Artist", Because he either knocks you out or you knock him out, there are no other solutions. I put him in front of his younger brother Sitthisak “Red Wolf” who is also a great puncher but less resistant. Thanongsak is young only 23 years old, so he has a bright future ahead of him and if he perfects a defensive style he could really be a huge problem at Light Flyweight. Special mention for Tewa Kiram, Nawaphon Kaikainha and Aran Dipaen who I appreciate and who always gives great fights.
Historically if we take all Thai boxers : 1- Pone Kingpetch 2- Samart Payakaroon 3- Chionoi 4- Veeraphol Sahaprom 5- Khaokor and Khaosai Galaxy
