Verdict
The clearest difference is rating: Aurelion Sentinel at 5.0 against PTSI Mobile's 1.5. Aurelion Sentinel also leads on update cadence (every 3 days vs every 6 months). PTSI Mobile's advantage is in-app purchases (none vs 4) and ratings volume (13 vs 2). On price, ads, monetization model and device support there is nothing between them.
