I know that GSBs get more love, but I gotta say that I am really enjoying shaving with a Gillette Platinum right now. I do understand that there are different Gillette Platinums and I couldn't tell you which one I have. I got it as part of the GBE. But I really do like it. And I would say that I like it better than the only GSB that I have tried. I'm not surprised that I like it, though, because I have also heard it said that it's similar to the King C. Gillette blade, and I love that one. Right now KCG, Wizamet, and PolSilver are my favorites that I have tried, but I like the Gillette Platinum - a lot.
Which blade are you discussing? Gillette Platinum Light Blue or Dark Blue? I've compared and found the Light Blue to be identical to the King C Gillette, and seen others reporting the same.
