Ibn, I wrote reviews for both of those oils, so in case you haven't read them, see if it aids your choice. I do not know what your personal tastes or preferences are, so if you could give some more detail of what you like in an oil, or what you tend to gravitate towards, then that would help.
Khidr is quite dark, while Idrees is the total opposite, it is bright sunlight. Both oils easily fit into the Indian profile.
If you want my honest opinion, Idrees has more to offer, and is a far more unique specimen. It is one of the top oils. You cannot afford to miss out on Idrees. So if you are going for one or the other, there is no question, in my opinion. Ideally, both deserve to be in everyone's collection.
