Any guesses?

The two shields WITHOUT a thick black line across the top are the Clearviews; the other two are stock Honda shields (OEM - not the tall Hondaline) with SAENG edging on them (the thick black line).

Personally, I see very little difference in optical quality.  To my eye, the Clearview gets the edge but only slightly.  Again, to my eye, there is a slight color difference: the Clearviews are lighter than the stock Honda shields.  I can see no distortion through any of the shields.
