Muay Thai, Boxing, Judo, BJJ, Kyokushin, and Sambo for the aliveness of their styles.
I'm with you though, I have to admit missing some of the cultural aspects of TMA. That's why to try to get the mental/cultural side down I am learning Tai Chi. I was an international affairs major(China) back in the day so the cultural aspect is important to me too. Good luck and don't be afraid to learn your preconceptions might be incorrect.
