For DE: Gillette 7 O'Clock Black Astra Rapira Stainless Rapira Sweedish Steel Voskhod For SE: Pella/EMS GEM
Gillette Black (Indian Super Platinums) Gillette Green Super Stainless (Russian) Barber Personnas I am planning a Blue vs. Black Gillette Super Platinum head-to-head soon, I am pretty sure one of those is going to be my bulk buying blade. OTOH, I've only tried about 8-10 blades. More to try! Interestingly I am not a fan of the Feathers or Gillette SharpEdge (Yellows). First shave or two is great, but they deteriorate too fast and then try to eat my face. No doubt they are sharp, but these others are plenty sharp for me and I get great, comfortable results in my EJ89.
I am really liking the Israeli Persona and the Gillette Super Thin (red pack) Thailand blades. They seem sharp and smooth.
I've been really digging these rebranded Personna Injector Blades...ie: Long's Drugs, EMS, and the CVS's have all been excellant. I love them...They are a little inconsistant but always at least as good as my favorite DE blades, and quite often I can't tell one from the old Schick Platnum Plus...and thats saying something...
When I first answered I only spoke of Injector blades, because I seem to be using the Injector soo often...But my Fav. DE blades would be: Perma-Sharp Super, Rapira, Astra, and for low-impact "3 pass-plus" shaves Wilkenson Sword...and Derby gets "honorable mention"
