I use zstd once a year, and it is very easy: 1. the default (3 on my machine) is fast and compresses well. 2. if you need to get the best compression level for your use case, use the benchmark "zstd -b1 -e15 yourfile" and after a few minutes you have your answer.

I can't see why I should ever in my life use another program for compressing things than zstd.
