Both do not have a good compression ratios; the right question being: is THIS compression type good for MY needs, thus, for MY type of data, and to solve that, the best way is to make tests as YMMV (knack spotted: if you're a professional in pictures &| films, do not event think about it.) Or, a fast solution could be to keep in mind that lz4 is so fast and so few CPU hungry that it seems to be quite a good compromise in many situations. (AFAIK, lz4 first makes a free run, observing if compression doesn't add to the original size and ditch it if so.) > So... where is the truth?
