I wouldn't say most. They both get plenty of love. That said, I prefer the blues too. They're a bit sharper.
Seller mysalonsupplies on ebay sells 200 superior stainless for $18.30 & free shipping. 10k feedback, 100% positive. I grabbed 600 myself.
i have 500 greens and 100 blues. i use the greens first because i have more,since my technique has improved i don t feel alot of difference between all my blades. they all work smoothly in my vintage gilletttes.all the blades i have fall into the smooth /sharp category.i don t use derby as they still pull,and i haven t tried anything sharper than a gillette platinum,which i use in my mildest gillette techs.
