How would you rate the following from 1-4 with 4 being the more sharp one ?

Astra superior platinum
7 o'clock super stainless ( Ru green)
7 o'clock sharp edge (Ru yellow)
Pol silver
 
Personally I put them all the same level with the yellow sharpedge just a tiny bit sharper still.
They're all sharp blades though so yellow pack at 4 and all the others joint 3.
