Raspbian is one that rings bells because it is based on the ARM, which probably no full-sized computer is these days (the Acorn Archimedes series used it almost thirty years ago). The range of Debian packages ported to the ARM RISC architecture is significantly smaller than those for i386 and amd64, so some things have to be done differently. The limitations of the system-on-chip which composes almost all of the Pi hardware imposes further limitations, compared to general-purpose desktop hardware or even laptop hardware. The relatively small storage space available again imposes restrictions. So Raspbian may well be quite different to a stock amd64 Jessie, utilising many of the tricks of older days of computing to make the best of limited hardware. -- Joe
