Different tastes. I normally use light olive oil to pop mine. Used coconut one night, hated it. I like coconut oil, but NOT for popcorn.
Coconut handles the high heat temps (like for popcorn) better than olive oil. I LOVE olive oil, too. I do use OO for my brown bag micro popcorn...if I have a micro as my only option.
The coconut oil has made popcorn (in my stove top, stir type popper) that friends and family clamor for ;) Different tastes...like you said ;)
