Verdict
The clearest difference is in-app purchases: Gravity One at none against Rocket Protector's 3. Gravity One also leads on ads (none vs shown) and update cadence (every 9 months vs every 24 months). Rocket Protector's advantage is iOS requirement (13.0 vs 18.0). On price and device support there is nothing between them.
