Depends what you want to achieve yeah?
If you want to power lift, why would you bother with any type of cardio?
Similarly, if you wanted to run marathons, why would you do anything but steady state cardio.
Really, it comes down to personal preference/what your goals are.
Personally I feel that weight loss/maintenance all comes down to energy expenditure, if you eat less than you use, you loose weight and vice versa.
Like running 10second 1/4 miles in a car, it doesn't matter what you do to get there, only that you get there.
Of course, that changes if you're training for competition or a sport etc. I thought it was interesting recently, reading a book on rowing coaching, one of the rowers made the observation that in the late 80s when the eastern Europeans were dominating, everyone in the west was caught up with HIIT training. Where as the east German teams were spending their time in long steady state pieces of 2 hours or more. Evidently, the base from steady state training helped them by giving them greater capacity in their high intensity training.
Just food for thought.
