Even more clueless than you
I use both Astra SS obviously and SP. Both I find good but SS are my preference as I find that they are a little smoother on my face. Other may find different. I not sure if the SS if they are sharper but my experience a little smoother.Astra SS is one of the blades that I ordered a sample of. Isn't it supposed to be sharper than the Astra SP? I ordered them mainly to compare with the SP's as I have the big pack of them.
Of course, I could wait a couple days and find out myself but I thought I'd ask how you think they compare
