The clearest difference is ratings volume: Subcap at 2K against Caption123's 6. Subcap also leads on iOS requirement (15.6 vs 17.0). Caption123's advantage is rating (4.8 vs 4.6) and update cadence (every 5 days vs fortnightly). On price, ads, in-app purchases and monetization model there is nothing between them.
