Currently running my own benchmarks, my preliminary results are that zstd becomes competitive again once you add the --long option (so `zstd --long -16 all.tar` instead of `zstd -16 all.tar`). Which is an option that not everyone might be aware of, but whose usefulness should be intuitive for this benchmark of >200 very similar files.
