Verdict
The clearest difference is in-app purchases: Rhythm at none against Sunrise's 2. Rhythm also leads on ads (none vs shown). Sunrise's advantage is update cadence (monthly vs every 13 months) and ratings volume (9.7K vs 458). On price, rating, review sentiment and device support there is nothing between them.
