I don't like the OVY either, but it has a unique prismatic sag glass that no other street light has. The OVF has an ordinary flat glass.
The OVF doesn't impress since it's horrible, but Cooper did manage to create an LED that really looks pleasing by taking the OVF and the OVH and turning them into LEDs instead of those other dreadful LED designs. The OVY is very cool, in my opinion, because of its prismatic sag glass.
