K1 is often better to watch, and indeed UFC is a bit too vulgar for me sometimes (kicking ppl on the ground), but it's the most versatile, and probably the most "real" of the martial arts... What i really dont like to watch (although i respect it immensely, knowing just how tough it is), is when it's just a grappling match that goes on for 10 minutes, with very little explosive action...
