Verdict
The clearest difference is review sentiment: BuildCores at 72% against Rust Notifications's 25%. BuildCores also leads on rating (4.7 vs 2.9) and ratings volume (2.1K vs 20). Rust Notifications's advantage is in-app purchases (none vs 13) and update cadence (every 2 days vs every 6 weeks). On price, ads and device support there is nothing between them.
