UFC or Boxing?

I prefer UFC than WWE. I was entertained before by WWE fights but not anymore. I appreciate Brock Lesnar for his willingness to transfer to UFC. Brock is an awesome fighter. Now, he is the undisputed Heavyweight Champion of UFC and I think he will hold that belt for years from now. He is really unstoppable because of his speed as heavyweight and his weight advantage over his opponents. I like to watch heavy weight fights at UFC. I have seen a collection of UFC heavy champions, http://sportales.com/martial-arts/ufc-heavyweight-champions-list/. This time, or even after two or three years, Brock Lesnar will be undefeated.
