You burn more carbs when doing cardio than aerobic, so surely aerobic exercise is better for weight loss? I think it's 50:50 carbs to fat for aerobic, and then the carb rate increases with effort. You'll burn more calories with cardio, but you'll be hungrier as you'll need to replace the carbs, so longer periods of aerobic exercise will burn more fat. E.g. If you burn 800 calories doing aerobic, then you'll have burned 400 calories of fat and carbs, but if you burn the same amount doing cardio, it'll be more like 600 carbs and 200 fat.
I do a lot of aerobic exercise alongside cardio to keep my weight down. I know of other people who get less time to work out, and so they inevitably turn every session into cardio or higher intensity, and then they get really hungry afterwards and go overboard with the calories they "replace" and don't tend to lose weight.
EDIT: By the way, what I mean by aerobic v cardio, is cardio being moderate intensity or above, with aerobic being low intensity to just below moderate.
