Which is better for your hair olive oil or argon oil and why ?

I have been doing hair for 35 years and have never tried either oils on any ones hair. However, I do use Moroccan oil. Not only does it make the hair feel great, but the oil is water soluble, so it is easy to wash out. They make an oil, shampoo, condition and cream. All are great and the shine and detangling properties are incredible.
