Verdict
The clearest difference is ads: Oberu at none against 75 Days Challenge's shown. Oberu also leads on update cadence (every 3 days vs every 2 weeks). 75 Days Challenge's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 26.0). On price and in-app purchases there is nothing between them.
