I picked ufc but I have spent the last couple months getting caught up on Pride. I saw the first five or so and thought the fights and fighters sucked so I quit watching, then Pride grew and gained good fighters and the others gained experience and I had to watch all the other prides I could get my hands on. I still prefer ufc but pride is excellent as well. I don't care for kotc as much as ufc or pride but still get the pay per views and have a ton of dvd's. I haven't had a chance to see Vale Tudo in 10-15yrs.
