if it works and there is evidence for it (what I mean is sparring in a "realistic" way) , and it is suited for you (some people do some style better,and the other not.And does it willingly or not.) it is a good martial art in my opinion.
And man it has to be fun too I think.You have to "like" what you are doing.
You may do MT but you are someone who watches kyokushin videos all the time and like them alot,love their style. you should go to a Kyokushin dojo.
thanks a lot for the information/opinions really helped
