Verdict
The clearest difference is rating: Contact Backup at 5.0 against Global Time Machine's 3.7. Contact Backup also leads on iOS requirement (10.0 vs 17.0). Global Time Machine's advantage is update cadence (every 4 days vs every 2 weeks) and ratings volume (7 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.
