Verdict

The call

The clearest difference is in-app purchases: Gravity One at none against Idle Universe's 7. Gravity One also leads on ads (none vs shown). Idle Universe's advantage is update cadence (every 3 weeks vs every 9 months) and iOS requirement (15.0 vs 18.0). On price and device support there is nothing between them.
