Exactly.

Whenever LZMA comes up people start discussing the differences and
then discuss what is THE best.
So far, IMHO there is NONE. Selecting the best filesystem is about
making trade-offs depending on what you need.

For example, the systems I use squashfs for, are intended to be booted
only *once* (or incidently after a firmware upgrade). I do not care
about the memory it takes, or if takes twice as long. Also, I need the
rootfs to be read-only. Distributing over any media and uploading
Linux/FPGA firmware over very slow device backplanes is my main
concern.
Squashfs w/ LZMA works best for me, because smallest. Kudos.

Linux, THE best if you need choice.
