While I agree in the sense that I have not seen evidence that reflective is better than emissive, I would rather see studies than depend upon ad hoc comparisons

While I agree in the sense that I have not seen evidence that reflective is better than emissive, I would rather see studies than depend upon ad hoc comparisons. The properties of a light source are typically different, the properties of surface reflecting or transmitting (for the lack of a better word) the light are different, and how the screen brightness responds to ambient light is different. There are many reasons why one type of screen may be better than another. The lack of compelling evidence simply means that there is a lack of research and certainly does not imply they are equivalent.
