Interesting example, but are you sure you're using equivalent values of 
roughness and phong_size? on the top 2 it looks like you've got a much 
smaller phong highlight than specular. I generally reckon phong_size 50 is 
equivalent to roughness 1/50.

One thing I've noticed about specular is it gets a hard line through it when 
you're using large highlights with rim lighting (i.e. lightsource behind the 
object). In this picture specular's on the left and phong's on the right. In 
this situation specular looks completely unrealistic IMO.
