GSBs with the Yellows a close second.
I have both GSB and Gillette Platinum. I have compared them side by side in identical razors during the same shave and cannot tell any difference between them. Thus, I believe they are the same blade in a different wrapper.
...Moral of the story for me is that any PPI (St. Petersburg) blade is going to be between good and outstanding...
Ditto!GSB, absolutely.
Smooth, sharp and long life, perfect balance.
