They have a nice table on that page: https://github.com/facebook/zstd#benchmarks https://github.com/facebook/zstd#benchmarks Looking at that table, I think LZ4 is a winner. The compression ratio is not too far, compression speed is slightly faster, decompression speed is significantly faster, the code is much simpler so the compiled binary is smaller, and the project is unrelated to Facebook.
