The parent article doesn't seem to be trying to be a fully fleshed out survey of compressors, but I found a separate comparison of zstd and Brotli: https://peazip.github.io/fast-compression-benchmark-brotli-zstandard.html https://peazip.github.io/fast-compression-benchmark-brotli-z... tldr: zstd seems to be somewhat more flexible, generally provides slightly better performance across almost all metrics, and decompresses much more quickly than Brotli.
