Verdict

The call

The clearest difference is in-app purchases: Space UWB at none against Breadpad's 3. Space UWB also leads on iOS requirement (16.2 vs 18.0). Breadpad's advantage is update cadence (fortnightly vs every 2 months) and chart position (#193 vs unranked). On price and ads there is nothing between them.
