Best example is still Holly Holm vs. Valentina Shevchenko, where we have a world champion in boxing going up against a world champion in Muay Thai. Holly got her legs chopped with low kicks and lost the kicking exchanges, then got her punches countered as well, and when it got to the clinch she was thrown around and taken down despite being an entire weight division bigger.
Then we have their fights against Amanda Nunes. Holly was out-punched, head kicked, and finished in under a round even though the Sherdog collective was convinced her boxing footwork would keep her safe and allow her to frustrate Nunes. Valentina went the distance both times and arguably won a decision in the rematch. But apparently, Muay Thai has no defence or footwork, so says the Sherdog hive mind.
Kickboxing, not Muay Thai. The only good boxer with nice Muay Thai is Jorge Masvidal, the rest of them are Dutch or Brazilian style kickboxers. This includes TJ, Overeem, Barboza, and the rest of the guys that are often referred to as Muay Thai fighters. They're not. None of them have a Thai style clinch game or strike selection.
As for Thai boxers with good hands. Shevchenko.
