I took it for a couple years, and it is kata heavy. I like the techniques TKD teaches though. Of course you are never going to bust out katas in a fight, but I just look at it as a system to help you learn the art. One thing I really liked was that we had the option of weapons training in my school. Of course I went with nunchucks!
I had fun in Tae Kwon Do. Kickboxing or Muay Thai may be more practical, but you can still pick up some good stuff from TKD, and it's good exercise!
