Verdict
The clearest difference is in-app purchases: 3MD CDL Prep at none against CDL Practice Test® 2026's 2. 3MD CDL Prep also leads on ads (none vs shown) and rating (5.0 vs 4.8). CDL Practice Test® 2026's advantage is ratings volume (6.1K vs 2). On price, update cadence and device support there is nothing between them.
