Verdict

The call

Pocket and Knowledge Observatory both sit at 4.9 stars, but that hides the real split: 100% of Knowledge Observatory's written reviews are positive against 67% of Pocket's. Knowledge Observatory also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). Pocket's advantage is ratings volume (7.4K vs 1) and chart position (#25 vs unranked). On price, rating, update cadence and ads there is nothing between them.
