Just take a look here: http://www.maximumcompression.com/
WinRK and Paq8 are the best compressors when size matters. KGB isn't as good as the best. There is also a nice comparison ranked on efficiency where WinRAR is one of the best.

In fact KGB is just an older version of PAQ (PAQ6v2) with a GUI on top of it. If you want the best possible compression you indeed have to look to PAQ8 (command-line) or WinRK (GUI).

PAQ8 has some nice tricks however like compressing embedded JPG images in DOC/XLS files etc.

Based on testings myself i see that WinRK actually do archieve a good compression ratio; and its pretty fast too.

Also thanks for the site; i find this stuff interesting :)

Yes, I test only programs that run under windows. But many of the *nix programs are ported to Windows. I did test Gzip, Bzip2 etc.

The programs you mention are decompressors, not the actual compressors.

Well you use the short form to compress and the long form to decompress, e.g. gzip2 and gunzip2, how good are they compared to the windows tools?

Not too good, have a look at gzip, bzip2 in the webpage below. Believe it or not, but compression is one of those application types where all research takes place on Windows Pc's. The last couple of years there were some major breakthroughs in compression caused by first PPM(d) and later the new PAQ context modeling algorithms.
