I use the King Deluxe 1200 and the Sigma Select II 6000 to sharpen my chisels and plane blades and on these stones O1 is the easiest to sharpen. I’ve found there isn’t that much of a difference between sharpening A2 and PM-V11. This could be because both my stones have a fairly friable bond and the continues release of fresh sharpening particles ensures they work fast and efficiently. Some also say you can’t get A2 as sharp as O1 or PM-V11 but in my experience that isn’t true. I can get A2 just as sharp as any other steel. All it takes is a steady hand and the right amount of pressure for each stone. I will say PM-V11 stays sharp a bit longer than A2.

I also really like the Quangsheng T10 carbon steel blades (T10 is the Chinese variant of W1, a water hardening steel) that come with the planes Workshop Heaven sells. These are hardened to 63RC and stay sharp a long time yet are still easy to sharpen. In fact, I like T10 more than O1, A2 or PM-V11. After losing most of it’s initial sharpness it feels a bit dull but it actually keeps going for a long time.
