pocon1, HIIT is to be incorporated WITH moderate duration cardio. They advise to only do HIIT 3 times a week and the other 2 days to do normal cardio. I agree that you will get a better cardiovascular benefit from doing longer duration cardio, however, when fatloss is your sole goal and you are already in good shape then HIIT is the best option. You also have to take into account that longer duration cardio eats away precious muscle, and HIIT doesn't (with proper post workout meal). I'm not sure about you, but most don't want to sacrifice their muscle... but like you said, it depends on what your goals are.
P.S. I wasn't reading too much into anything, I was aswering discostu's post
