Verdict

The call

Breadpad and Tin Toy both sit at 3.9 stars, but that hides the real split: 100% of Tin Toy's written reviews are positive against 33% of Breadpad's. Tin Toy also leads on in-app purchases (none vs 3). Breadpad's advantage is update cadence (fortnightly vs every 3 months) and ratings volume (166 vs 1). On price, rating, ads and device support there is nothing between them.
