By exploring SJR we have H-Index which is defined as "The h-index is defined as the maximum value of h such that the given author/journal has published at least h papers that have each been cited at least h times." as in https://en.wikipedia.org/wiki/H-index.
while the cite-score is defined as "CiteScore (CS) of an academic journal is a measure reflecting the yearly average number of citations to recent articles published in that journal."
The two definitions show resemblance to some extent, but the values are very different.
What do you think?: Which is better to consider H-Index or Cite-score?
