Verdict

The call

Osmosis and GCLEX both sit at 4.8 stars, but that hides the real split: 100% of GCLEX's written reviews are positive against 47% of Osmosis's. GCLEX also leads on update cadence (every 3 days vs monthly). Osmosis's advantage is ratings volume (3.9K vs 8) and chart position (#57 vs unranked). On price, rating, ads and in-app purchases there is nothing between them.
