Verdict
The clearest difference is in-app purchases: Grades! at none against Earth 3D Globe's 4. Grades! also leads on ads (none vs shown). Earth 3D Globe's advantage is update cadence (every 11 days vs every 86 months) and iOS requirement (16.0 vs 26.0). On price and device support there is nothing between them.
