Compression Software, 7z vs UHA vs KGB

There are many compression software available both commercial and open source. Commercial software always sucks and do not really have tweaked and community demanding features.

Being an open source geeks, I am addicted to use 7z and it always make me happy. But in some cases for some other formats other tools perform very well. UHA and KGB archiver are very popular in this regard. Below is the detailed comparison of these three products.
