Verdict
The clearest difference is in-app purchases: GAPP Guidelines at none against IMAIOS e's 2. GAPP Guidelines also leads on iOS requirement (9.0 vs 16.6). IMAIOS e's advantage is update cadence (every 9 days vs every 5 months) and chart position (#139 vs unranked). On price, ads and device support there is nothing between them.
