PowerArchiver allows to choose between different compression formats (deflate, LZMA, BZ2..), send automatically the archive by email, FTP or burn it to a disc (CD/DVD/Blu-ray). It provides different encryption algorithms to choose from when you set a password for an archive.
It allows to create .rar archives through its interface, only if you have WinRAR already installed on your computer. There are only a few programs that allow to create .rar archives, because the license to build this type of archive is paid. This may be a reason why .zip extension is more popular than .rar.
