Verdict
The clearest difference is in-app purchases: RouletteBox at none against SoundEffect App's 4. RouletteBox also leads on iOS requirement (12.0 vs 16.0). SoundEffect App's advantage is update cadence (fortnightly vs every 6 months) and rating (4.7 vs 4.3). On price, ads and device support there is nothing between them.
