This question prompts the discussion to explore the nuances and implications of using Scopus and Web of Science for research evaluation and assessment.
In principle, since Scopus has more publications in it, it is to be expected that indizes like the h index in Scopus should be higher than in WoS, except of course if Scopus makes an error such in this baffling case: https://www.researchgate.net/post/How_do_I_calculate_H-index_in_Web_of_science
These indizes, however, are sort of a tool which was designed to help the scientists but are now used for position choices so it has sort of turned against them. Running after a high h index can encourage bad behaviour ranging from "small step publications" up to citation cartel formation. With respect to the impact factor Clarivate (the company behind WoS) has publicly stated that the impact factor should not be a criterium for job assignments, but that is certainly the case.
