Verdict
The clearest difference is in-app purchases: Gravity One at none against Mission's 3. Gravity One also leads on ads (none vs shown). Mission's advantage is update cadence (weekly vs every 9 months) and iOS requirement (11.0 vs 18.0). On price and device support there is nothing between them.
