Verdict
The clearest difference is review sentiment: SDG Athletics at 100% against Glofox's 36%. SDG Athletics also leads on rating (5.0 vs 4.5). Glofox's advantage is ratings volume (272 vs 3) and update cadence (every 2 months vs every 9 months). On price, ads, in-app purchases and monetization model there is nothing between them.
