Muy Thai vs MMA who will win?

It depends on the situation... If you have a pure muay thai fighter fight in a MMA fight against a MMA fighter, he will loose and vice versa, same goes for boxing and MMA and many other combinations.

Since MMA (or Mixed Martial Arts) is a combination of all martial arts, and everyone is different, it is really best to start with at least one pure Martial Art, and Muay Thai is a great one to start with. Most of the striking in MMA comes from either Muay Thai or Kenpo Kickboxing. Muay Thai also adds the elbows as weapons, so ground and pound is based on a hybrid of keeping an opponent on the mat (Jiu-Jitsu) and striking them (Muay Thai) with elbows, hammer fists, and knees (where permitted). My suggestion would be to start with Muay Thai, and if you don't have much of a wrestling background, find a good Gracie-based Brazilian Jiu-Jitsu school in your area. In a few years, you could be ready for Mixed Martial Arts. Going straight into MMA is like going into a gunfight bare-handed: yes, you have the instinct to fight, but no tools to do it with. Good luck with your training, and DO NOT QUIT! Even if you find that you aren't MMA material, Martial Arts is great for disciple, fitness, and self-confidence.

I would recommend taking Muay Thai, and if you want to eventually learn MMA, you will already have striking experience; most of the decent MMA gyms I have seen generally prefer that you train in Muay Thai and BJJ separately before taking the MMA courses.

In muay thai you have punches kicks elbows knees, headbutts, and clinching, the only thing thats different between the two is the grappling, mma, is mixed martial arts, so you could go in doing capoeria if you like. However muay thai is very strong and god.

Take Muay Thai so you have a solid foundation in standup, then take MMA after a few years.

most MMA fighters train in muay thai and jiujitsu. some of them do train in other martial arts also. muay thai is just kickboxing. punches, kicks,nees, and elbows. in MMA you will do all of the punches and kicks, but will also have grappling incorporated into it. the main difference between the two is the grappling. if you take MMA then you will also learn how to fight on the ground too.

i would in a good tai boxing school because for me it seems its very strong and aggressive

muay thai is mma

The better class would win...... for you.

Styles don't make fights, it's up to the practitioner.
