ZSTD seems to be relatively revolutionary in the field of compression, at least in most of the test cases I've tried. Binaries typically compress as well as LZMA2, averaging about a 50% compression ratio, with nearly an order of magnitude faster decompression.
ZSTD beats DEFLATE and Gzip seemingly in every metric. It decompresses faster than almost any algorithm out there, save maybe LZO or LZ4, and has a compression ratio comparable to much slower algorithms.
Arch Linux switched to ZSTD for compressing their package database at the beginning of this year, and only increased the overall average compressed size by 0.8%, while speeding up decompression several orders of magnitude compared to LZMA2.
