# Block Mania vs React CRT

The clearest difference is review sentiment: React CRT at 100% against Block Mania's 26%. React CRT also leads on ads (none vs shown) and rating (5.0 vs 4.7). Block Mania's advantage is ratings volume (2K vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.
