Verdict

The call

The clearest difference is rating: Perfect Structure at 5.0 against BIM 360's 1.8. Perfect Structure also leads on update cadence (every 2 days vs every 6 weeks). BIM 360's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price, monetization model, device support and iOS requirement there is nothing between them.
