Verdict
The clearest difference is rating: Summit Reader at 4.8 against Interchange's 4.3. Summit Reader also leads on monetization model (free with in-app purchases vs subscription) and review sentiment (86% vs 73%). Interchange's advantage is ads (none vs shown) and update cadence (every 6 days vs every 3 weeks). On price, in-app purchases and device support there is nothing between them.
