Verdict
The clearest difference is review sentiment: Planet Gravity at 44% against Rocket Simulator's 11%. Planet Gravity also leads on rating (4.2 vs 3.8). Rocket Simulator's advantage is update cadence (every 2 months vs every 6 months) and monetization model (free with in-app purchases vs paid). On price, ads, in-app purchases and device support there is nothing between them.
