Difficult to say 'the best', but the most popular is probably gzip(.gz),
bzip2 (.bz2) is also well used and gives a higher comression ratio.
The trade off is in compression/decommpression time, and memory usage.
Almost all source distributions use tar files compressed with either gz
or bz2.

There are Zip and RAR versions for Linux too.

For speed, there's the lzo library (and it's UI: lzop), but it isn't
much used. If you are building an application that needs fast
compression then the lzo library is faster an alternative to zlib.
