Verdict

The call

The clearest difference is in-app purchases: Article Zero at none against ER's 2. Article Zero also leads on update cadence (daily vs every 6 days) and ratings volume (7 vs 1). ER's advantage is ads (none vs shown). On price, rating, device support and iOS requirement there is nothing between them.
