Verdict
The clearest difference is ads: Did You Know.. at none against Traitus's shown. Did You Know.. also leads on update cadence (every 5 days vs every 2 weeks). Traitus's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.6). On price and in-app purchases there is nothing between them.
