Verdict
The clearest difference is rating: Planets AR at 5.0 against Encyclopedia's 3.8. Planets AR also leads on update cadence (daily vs every 62 months) and review sentiment (100% vs 83%). Encyclopedia's advantage is ads (none vs shown) and ratings volume (14 vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.
