Peronally I started Boxing with my Dad as a child,in high School I got into the Wrestling Team.During High School I starting trying to Learn Muay Thai off Book sources,internet,Friends training in it and Regular Kick Boxing and so on until I actually found a Place to learn it at 19,I also Officially started training in Muay Thai just 2 months before BJJ.I'm 20 now.
In the Years Between all of this and after I Did alot of Heavy Sparring with Friends that studied Different Arts.I want to go Pro in UFC and Pride someday soon.....
Personally IMO and most MMA fighters TKD can be to flashy for MMA sometimes.The Muay Thai Round house and low Round House Kicks are Built For Power and are as fast as any Round house kick can be while still having power.TKD is not about power but style,Speed and Points(for competition).So a Good M.T. Round House kick will always be more Powerful and effective then a TKD Round house kick.Its just the physics behind it, a TDK Round house Doesn't use the Hip Movement and Body weight behind it the way a M.T. Round house kick does.Also your Typical Muay Thai stance(Very much liek the Boxing stance) has a much better Defensive Position just like Boxing and Would Make most TKD uneffective.Much like a Good Boxing Stance will stop most Round kicks to the head because the Defensive stance is already blocking the Upper Body Even though its a punching style a Boxer moving in on a TKD expert will murder him at close range and a long distance fight won't work to long on a regular boxer because all he has to do is close the distance and walking and blocking do that just fine,lol.As Long as a M.T. Fighter has good Take down Defence he is Perfect,of Course M.T. is nothing on the Ground.So BJJ is still the Best Ground game to learn.But learn both and your well rounded in a short amount of time.
In addressing your comparison of TKD kicks vs. Muay Thai kicks, I'll have to disagree. See: Roundhouse kick - Wikipedia, the free encyclopedia
As you can see there, both Muay Thai and TKD kicks involve both hip and body rotation. The main difference between the two is that Muay Thai uses more momentum, whereas TKD kicks are more focused on the rotation and "snap" motion at your knee. Muay Thai takes less leg strength to achieve more power (As it has much to do with weight and rotation), but it also is easy to read and spins you completely around if you miss. If someone who is experienced in kicking see's it coming, they're going to wait for the rotation and catch your back.
For that reason, I prefer the TKD kick, as you can kick and miss without losing your position. You can also get plenty of power behind it - Currently I've sent 2 opponents home with dislocated arms and one with 3 separated ribs through his pads. Through leg training and proper rotation and snap technique, you can learn to kick extremely hard without losing your position or getting off balance. The balance along with the exaggerated motion are big qualms I have with a MT kick, as well as the fact that a MT kick has you on the ball of your support foot (Making it extremely easy to just push the guy over if you can avoid the kick).
Your point about TKD teaching poor stance versus anything but another TKD opponent is very valid though. I agree completely. TKD focuses very lightly on protecting yourself from boxing techniques, whereas MT incorporates boxing, dirty boxing and kicking into its techniques. That is why I stated that MT is the faster way to go in learning MMA standup.
For me, I had to learn TKD to kick, boxing for proper hand work, and then had to personally work the two together. I've come out with a finished product that I'm pleased with, and was glad to do it as I enjoy the TKD kick, but learning just Muay Thai would have saved me a lot of time. =)
