Verdict
The clearest difference is rating: decimal3D at 5.0 against CT Anatomy's 4.5. decimal3D also leads on in-app purchases (none vs 1) and update cadence (every 2 months vs every 22 months). CT Anatomy's advantage is ratings volume (126 vs 3) and device support (3 vs 1). On price and ads there is nothing between them.
