IMO flavacol is essential. Oil type matters too, coconut oil gives more of a movie theater style flavor (OTOH maybe not as healthy as other options...)
You're probably thinking of the MCTs in coconut oil, which do seem to offer some health benefits, but coconut oil is also monstrously high in saturated fats (90% vs 14% for olive oil), and tons of studies show that saturated fat is relatively awful for the human body.
