Verdict

The call

The clearest difference is review sentiment: ChessLine at 100% against Aimchess's 51%. ChessLine also leads on rating (4.9 vs 3.9) and update cadence (every 10 days vs monthly). Aimchess's advantage is ratings volume (195 vs 7). On price, ads, in-app purchases and monetization model there is nothing between them.
