Verdict
The clearest difference is in-app purchases: Call Checker at none against Check Book Register's 10. Check Book Register's advantage is update cadence (every 9 days vs every 23 months) and chart position (#148 vs unranked). On price, ads, device support and iOS requirement there is nothing between them.
