These tools sit in different sets (Research assistant vs Academic search), so picking one over the other is mostly a question of which job you're doing. Semantic Scholar wins on citation honesty, source quality, privacy controls, speed, and value for money; the rest is a wash. Both pass our quality gate. The right pick is the one whose strengths match the job you're trying to do.
