Verdict

The call

The clearest difference is review sentiment: E at 90% against CX's 36%. E also leads on rating (4.7 vs 3.7) and update cadence (every 2 months vs every 8 months). CX's advantage is price ($19.99 vs $24.95) and chart position (#68 vs unranked). On ads, in-app purchases, monetization model and device support there is nothing between them.
