WinRAR vs Zip vs 7zip vs Others

[mr.slooz]

Winrar uses various filters (compression alogs for diff. sources), 7zip not. Personally I prefer 7zip. But if you guys want test one of the best packer, test nanozip hxxp://nanozip.net/ it is really good.

That's actually not true - 7Zip also supports filters (x86/x64 executable code, PPC, IA64, ARM, SPARC, delta filter).
WinRAR dropped support for most of the specific filters in v5 (from the changelog: "RAR 5.0 format includes Intel IA-32 executable and delta compression algorithms, but RAR 4.x text, audio, true color and Itanium algorithms are not supported. These excluded algorithms are not efficient for modern data types and hardware configurations").
