Verdict
The clearest difference is ads: Mekong Science at none against Grade 12's shown. Mekong Science also leads on update cadence (every 2 months vs every 9 months). Grade 12's advantage is iOS requirement (13.0 vs 16.4). On price, in-app purchases and device support there is nothing between them.
