I don't consider any of those forms to be superior to each other. What's most important during every loss weight is calories deficit.
I'm able to lose weight without doing cardio or HITT at all, it doesn't really matter, but I prefer to eat more and do some cardio and HITT, that's why I usually end up doing doing them.
If we look from weight loss perspective only HITT is probably superior, but only because body adapts to cardio much faster than it does to HITT and as only semi-advanced people are able to perform HITT correctly, most of them is already pretty much used to doing cardio, because people tend to overdo it pretty often.
So, only because of that reason, I would put HITT a little bit higher than I would place cardio.
