Verdict
The clearest difference is in-app purchases: OptClass at none against Abacus Simulator's 10. OptClass also leads on update cadence (every 2 days vs every 3 weeks). Abacus Simulator's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price and ads there is nothing between them.
