ah, thanks. A German magazine I read (C't) said, that the 4900HS is exclusively used by Asus for a while. Would be a shame if true :/The H seems to only have a higher base clock than the HS (3.3GHz vs 3.0). Turbo is almost the same. I doubt you'll notice anything in real life. I would pick the HS and enjoy the longer battery life, which will be noticeable.
There's an overview of the processors and the laptops who use it at https://www.ultrabookreview.com/35985-amd-ryzen-4900h-4900hs-laptops/ There is a 15" and 17" ASUS TUF Gaming that use the 4900H.
