Verdict
The clearest difference is rating: CertsCheck at 5.0 against ServerCat's 4.6. CertsCheck also leads on review sentiment (100% vs 77%). ServerCat's advantage is ratings volume (1K vs 4) and update cadence (every 5 days vs monthly). On price, ads, in-app purchases and monetization model there is nothing between them.

CertsCheck holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: ServerCat has 1K ratings behind it against 4, so its average is the more settled of the two.
