I know at least one old timer who has been around here since the beginning who has always said that he has 4/8 blades that shave as well as any other out there and that they would always be in his collection.......
Now there certainly is a lot of personal preference in this sport too.

One of my very best razors is a 4/8 Puma. I like it so much I got another one. It shaves like a dream!
