Verdict

The call

The clearest difference is rating: AutoCAD at 4.4 against CtrlSun's 1.0. AutoCAD also leads on ratings volume (6.3K vs 1). CtrlSun's advantage is in-app purchases (none vs 3) and update cadence (every 3 weeks vs every 2 months). On price, ads and device support there is nothing between them.
