Am I in the Minority or is it just in my head. For the most part all blades are about the same. Some are obviously a little sharper then others. But to really notice the blades’ performance you have to shave against the grain. Shaving wtg and cross the grain for the most part all blades feel about the same.
In my experience I've had mixed results with different brands. I have found the Silver Star and Merkur blades to be very good and the Bic blades very good for subsequent shaves after the first one. I have found the Treets and Voskhod blades pretty poor all round, so in my experience there are clear differences between different brands. As the saying goes, YMMV.
