Are all compressors simply being run with their default arguments? There's a lot of scope for speed/filesize tradeoffs within a single compressor.
EDIT: You are missing `csv+zstd` ? It should obsolete `csv+gzip` at all speeds and compression levels.
There is a pareto-optimality frontier here - I ran my testing back in 2016 https://code.ivysaur.me/compression-performance-test/ but the numbers are now a little bit obsolete (e.g. zstd and brotli have both seen a lot of improvements).
