Sorry if this is a dumb newbie suggestion, but for matching journals in different datasets via ISSN, I think adding ISSN-Ls to each dataset, then matching on that, might catch more overlap. I've seen cases where WoS and Scopus have chosen different ISSNs for the same journal. The conversion table can be obtained here:

or I suppose could be scraped from individual entries.
