I agree that super steels are possibly a bit better in daily use. But the real benefit of the super steels accrues to the knife makers through their marketing.
I don't see any difference between them in my uses anyway. You of course realize that these new "super steels" are only meant to get you to buy the latest and greatest steel. Many years ago I was really into the audiophile thing and keep buying the latest equipment. Especially the receivers that kept going down and down in the distortion figure. I then happened to read that for the last several years the distortion factor was lower than the human ear could detect. Its getting that way with video, 8K seems to be the top one for your eyes. To be frank the VG10 does everything I need, but I keep on buying other steels(just human after all).
