Close to perfect
My favorite blade is the Merkur platinum coated. It’s the perfect balance of sharp and smooth for my tastes. But they’re pretty expensive, so my go-to alternative is the Dorco 301 about 1/8 the price. This Parker blade is only a little more expensive than the Dorco (if you get the 100-pack), and is almost as good as the Merkur. The Parker is as sharp as the Merkur, but not quite as smooth, so it comes across as a little more aggressive in my Merkur 23C. It’s not perfect but it’s pretty close.
