I will be no help here at all. I am firmly and comfortably on the fence. The Astra SP and Personna Super (Lab) are my "top" go-to blades. I keep thinking I can settle on THE ONE but to no avail. For me (IMO) they are both great blades with indistiguishable differences (YMMV). I give a nod to the Personna Labs on convenience for the convenient 100-pk dispenser box and no glue dots on the blade. The Astra gets the nod for best price/blade. Once loaded in the razor, they are both a tie for Top Gun!
