The verdict

R Discovery wins, 6.5 to 6.0

Semantic Scholar is free, with no paid plan; R Discovery's cheapest paid plan, Prime, is $12 a month. R Discovery answers back with things Semantic Scholar does not have: a native iOS and Android app, a written literature review draft, and unlimited translation on the Prime plan. Semantic Scholar counters with a free, documented API, the most substantial in the category, and direct integration with Zotero, Mendeley and EndNote.

Pick R Discovery if you want a mobile app, translation or a written review draft.

Pick Semantic Scholar if you want a free plan with an API and reference manager sync.
