Verdict
The clearest difference is ads: Countdown at none against Birthday Reminder's shown. Countdown also leads on device support (4 vs 2) and iOS requirement (12.0 vs 16.0). Birthday Reminder's advantage is update cadence (every 2 months vs every 6 months). On price and in-app purchases there is nothing between them.
