Verdict

The call

The clearest difference is rating: Upgradors at 5.0 against Starfall's 4.1. Upgradors also leads on update cadence (every 5 days vs every 2 months) and review sentiment (100% vs 73%). Starfall's advantage is monetization model (freemium vs subscription) and ratings volume (4.4K vs 4). On price, ads, in-app purchases and device support there is nothing between them.
