Verdict

The call

The clearest difference is in-app purchases: WSI Pilotbrief Optima at none against VAAC's 1. WSI Pilotbrief Optima also leads on update cadence (every 4 months vs every 11 months) and review sentiment (15% vs 0%). VAAC's advantage is device support (3 vs 1) and iOS requirement (9.3 vs 17.6). On price, ads and monetization model there is nothing between them.
