The clearest difference is rating: CuriosityStream at 4.6 against Caliban Below's 3.8. CuriosityStream also leads on ratings volume (6.3K vs 13).

CuriosityStream holds the better App Store score, 4.6 against 3.8.

Written reviews complicate that: 31% of CuriosityStream's written reviews are positive against 60% of Caliban Below's, so the app with the better star average is not the one people write more warmly about.
