Verdict
The clearest difference is rating: 3dMaster at 5.0 against Reality OBJ's 4.2. 3dMaster also leads on iOS requirement (15.0 vs 17.0). Reality OBJ's advantage is ads (none vs shown) and update cadence (weekly vs every 2 months). On price, in-app purchases, monetization model and device support there is nothing between them.
