7z has way better (ultra) compression
7z has way better (ultra) compression
I still prefer 7z for compression
7z uses proprietary rar library to unpack
7z can be at least decompressed in macOS & FreeBSD out of the box.
On windows tar.bz/gz/xz unpacks to tar and then to actual files. As tar is a separate archive format
7z was developed in 1999. As far as I know, rar was popular due to was shareware with practically unlimited “trial” and there was an opinion, that paid products are better.
Following this logic whole human life is a puzzle game.
