Depends on what you mean by best:

 - bzip2 will compress larger text files very well, but it has poor
   latency and uses up a good bit of memory, and lots of CPU.
 - zlib/gzip/zip (same algorithm, different formats): better latency,
   good overall compression (but not as tight as bzip2), still quite
   a bit of memory and CPU.
 - arithmetic coding: really good compression, but patented.
 - various other things, like LZ77-derived compressors, are often faster
   and/or more memory/CPU efficient and/or have better latency.
