Verdict
The clearest difference is ads: BELFOR University System at none against CDL Prep's shown. BELFOR University System also leads on update cadence (fortnightly vs every 2 months) and rating (5.0 vs 4.7). CDL Prep's advantage is ratings volume (7K vs 4) and chart position (#78 vs unranked). On price, in-app purchases and device support there is nothing between them.
