Verdict
The clearest difference is ads: Task Calendar at none against Yoko Timeline's shown. Task Calendar also leads on iOS requirement (15.1 vs 17.6). Yoko Timeline's advantage is update cadence (daily vs every 10 days). On price, in-app purchases and device support there is nothing between them.
