Verdict
The clearest difference is in-app purchases: Alliance Global at none against Comet's 3. Alliance Global also leads on rating (5.0 vs 4.7) and iOS requirement (16.0 vs 18.0). Comet's advantage is update cadence (every 8 days vs every 21 months) and ratings volume (7.8K vs 1). On price, ads and device support there is nothing between them.
