NetBSD vs SparkyLinux

It adheres to traditional Unix and new defined standards.

It's open source with a BSD License, which is much more business friendly than GPL. It's the real ancestor of Mac, that is being used nowadays.

Under NetBSD csh is csh not tcsh; also vi is real vi not elvis, nvi or vim. It's ideal for purists.

It's the most portable OS in the world when considering what architectures it can run on. It runs on very wide range of hardware, from toaster to satellites. This of course does not mean it supports drivers for many consumer facing products making it a difficult solution to just boot up and use when compared to other OSs.

It prioritizes source code cleanliness over anything.

You have access to a large user repository, Ubuntu guides can mostly be applied since both are based on Debian.

You have the option for Sparky to be based on Stable or Non-Stable, bringing greater flexibility to user priorities.

Sparky is designed to be lightweight in it's core. It is based on Debian but optimised for old hardware, meaning you can run a full heavy desktop environment on a lightweight foundation, bringing greater performance compared to similar Debian or Ubuntu-based distros.

Any Linux desktop in it's vanilla form can be installed on top of Sparky, whether that be alongside a pre-existing environment, or on top of a basic command line system. Furthermore, the command line system is easy to operate due to Sparky's advanced installer utility, from which you can choose whichever desktop environment you desire, straight from the Debian repositories.
