Tried a couple I had from a sampler when I ran out of my personal Gold Standards: Wilkinson Sword. Felt like I was using a really old, used blade right out of the box--twice. FWIW, I have an average Caucasian beard & skin and use a Merkur 34C with H.I.S. Shave Oil (AMAZING stuff if you haven't tried it yet..!) and have done well with Feather, WS, and Gillette Platinum. Hope it's a worthwhile data point in your search for perfection.
