Your Mileage May Vary I have course facial hair and sensitive skin. I shave with either a Wolfman WR1, a Mühle R41 or a Weber polished head.
Most of the Gillette/P&G blades I've tried (all purchased before their toxic masculinity debacle) have been pretty good/really good. (PolSilver Super Iridiums like Feathers are too sharp for me.)
Below are the blades I've tried that are not P&G.
Voskhod / Rapira Platinum Lux work really good for me.
Personna Lab Blues / Rapira Swedish Super Steel work pretty good.
Sputnik / Ladas / Rapira Stainless / Rapira Super Stainless are just meh.*
Feathers are too sharp and not smooth enough. I tend to get cuts and irritation when I use them.
Derby Premium are not good.
Shark Super Stainless / Wilkinson Sword (German) (from Walmart) are horrible.*
*listed best first

Voskhod and Shark! I've actually lost count of how many shaves I have on this current shark blade, it just keeps on cleanly shaving...

Just goes to show how true YMMV is. The Voskhod is my personal favorite in my Mühle R41 and among the top in my Weber PH and my Wolfman WR1 but the Shark Super Stainless blades are horrible for me in all of them. Even when new I can feel the Sharks tug my coarse beard hair and three shaves from them is all I can force myself to do before they get so bad that I have to replace them (like a dummy I bought a hundred pack and have been forcing myself to use one blade a month to use them up). I have given some to a few people I know that shave with a safety razor, along with other blades for them to sample, so they could try them out to see what blades might work for them but of the ones I have asked how they felt about the blades I gave them to try they said that the Sharks were among the worst.
