Eh I think they’re two different markets. If you prioritize health over taste, go for the cheaper, natural rapeseed. If you’re prioritising taste over health, most people are not going to be bothered by the sat fat, and would prefer an unadulterated flavour.
I believe you have to distil the oil, so it’s definitely going to be heated. You can be sure that the processing required to remove the sat fat is going to change the flavour and texture, while also somehow making it worse for you than either.
