LZ4 is faster but ZSTD compresses better. They're both viable on ZFS, but it depends on your usecase. Notably BTRFS does not offer LZ4, and in the case of BTRFS I would really only recommend ZSTD, as LZO is just not worth it.
Edit: Found some benchmarks you can look through: https://docs.google.com/spreadsheets/d/1TvCAIDzFsjuLuea7124q-1UtMd0C9amTgnXm2yPtiUQ/edit#gid=0
Amazing. Thank you. It's awesome that zstd has caught up in encode/decode time. There was a solid 5-10 years there nothing came close to lz4 in both.
