Well, for toast compression the right choice is definitely one of the
lz based algorithms (not libz!). For transport compression you have
the case of sending large data over very slow and/or expensive links
in which case you want to use bzip type methods. But in the majority
of cases I'd probably be using lz there too. So if I had to pick just
one, there you go. But which one? the lz algorithm with arguably the
best pedigree (lzo) is gnu but there are many other decent candidates,
some of which have really tiny implementations.
