Verdict
The clearest difference is ads: Brush marks at none against Mojo Handbook's shown. Brush marks also leads on update cadence (every 4 days vs every 2 weeks). Mojo Handbook's advantage is iOS requirement (13.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
