Verdict
The clearest difference is in-app purchases: Stardust Harmonia at none against DeltaBeats's 8. Stardust Harmonia also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 85%). DeltaBeats's advantage is ads (none vs shown) and ratings volume (11 vs 1). On price, update cadence and device support there is nothing between them.
