Of the three brands mentioned, I've owned a wustof classic for ~15 years, and have used various globals. Advantage of the wustof is that it's very well balanced/easy to handle, mostly easy to sharpen, and solid/strong for something so versatile - no issues using occasionally on bones, or an ah-hoc can opener. However the bolster does make it harder to sharpen the last cm or so of the blade, and that bit tends to get more worn after a few years, which changes how you use it.
The globals are lighter, and quicker on fine cuts. If you get on with the handles, they're very comfy/easy to use, and if you don't they're awful. They use a very hard steel throughout, making them easy to sharpen if you keep them sharp, but a nightmare to recover the edge if they go blunt.
I think we have different ideas of hardness, globals are only 56-58 hrc, most Japanese knife steels are considerably harder, something like a fujiwara denka is 66-68 hrc
