Verdict
The clearest difference is in-app purchases: Twilight Time at none against Binary Clock's 1. Twilight Time also leads on iOS requirement (16.7.10 vs 26.0). Binary Clock's advantage is ads (none vs shown) and update cadence (daily vs every 2 weeks). On price and device support there is nothing between them.
