There are a lot of blades out there and I certainly have not tried them all or anything even approaching it however over the years I've found the feathers to be second to none no matter the razor they are in (well maybe not in the original R 41). The Gillette yellows are good blades though I've found them to be on the rough side depending on the razor and the Astras have been decent.

These days I only use the feathers. Even with the timeless which is on the aggressive side they work really good. You just can't push more than 3 shaves from them.

I wish they still made blades like the original Willkinson stainless from the 1960s. Ten great shaves guaranteed from those babies.
