I recently tried 5. For me, they are now #3 on my top 3 list, displacing Astra. Great shaves but unlike my WS and Feather blades, they feel as if they want to bite me.
I have some that I bought a while ago. The Silver Blues. I have yet to use them. I can't say I've ever had a really bad blade. I tend to use Derbys and Wilkinsons these days and am pretty happy with them. I really don't notice much difference between the various brands I've used, but the occasional dud exists. Not a fan of Merkurs, but have no issue buying or using them if that's my only option.I recently tried 5. For me, they are now #3 on my top 3 list, displacing Astra.

btw, Astra's are also Russian Gillette blades (that is, made in the same St. Petersburg plant). Which Russian Gillettes: yellows, dark blues, or greens (which are yellows without edge coating), or others?
