Verdict

The call

The clearest difference is ads: Dabble at none against DSUController's shown. Dabble also leads on review sentiment (75% vs 63%) and monetization model (free vs ad-supported). DSUController's advantage is update cadence (monthly vs every 6 months). On price, rating, in-app purchases and device support there is nothing between them.
