I think it's better to use refined coconut oil rather than olive oil. Coconut oil has a higher heat point, meaning it can withstand higher cooking temperatures compared to olive oil.

I think it's actually healthier to use olive oil only for drizzling on salads and not heat cooking with it; however, olive oil may be healthier to use than corn oil. The problem is exposing the olive oil to high cooking temperatures and the risk of destroying the healthy fatty acids in the oil.

Unrefined coconut oil is the purest form of virgin coconut oil you can use. It has all the highest amount of healthy fatty acids in the oil since it has the least exposure to heat and other processing methods used in refined coconut oils.

Refined coconut oils may be exposed to higher heat or other methods for purifying the oil; this is why a lot of refined coconut oils lose their coconut scent and flavor - it has been processed out of the oil.

Refined coconut oil is good to use if you don't want that added scent and flavor of coconuts in your dishes.

Unrefined coconut oils will impart that tropical coconut oil scent and flavor to your dishes.

Which one to use will depend on your own cooking choices and if you want the flavor and scent of coconuts in your dishes.

I think Spectrum is one of the better natural oil companies. You can read more about them in my review of Spectrum coconut oils.
