When comparing Deepin OS vs Nix os , the Slant community recommends Nix os for most people. In the question“What are the best Linux distributions for a backend developer?” Nix os is ranked 4th while Deepin OS is ranked 15th. The most important reason people chose Nix os is:
It has all of hackage in it's package manager (which is confusingly named "nix" as well) due to being based around hashing and allowing you to compile in a sort of virtual machine (really just changing the PATH variable temporarily) it solves many of the versioning problems that you commonly have with cabal. Here's a tutorial (there's many others as well) http://www.cse.chalmers.se/~bernardy/nix.html. Also I should note that you can use the package manager a la carte on Mac and most any linux distro.

Here's a tutorial (there's many others as well) http://www.cse.chalmers.se/~bernardy/nix.html.
Also I should note that you can use the package manager a la carte on Mac and most any linux distro.
Pro Upgrading the system is extremely reliable
Since NixOS stores all its packages in isolation from each other in /nix/store
and because of the declarative configuration model, upgrading NoxOS systems is extremely reliable. Furthermore, it gives you the ability to roll back upgrades.

Every package in your system is generated from a configuration file. This makes it very easy to reproduce that environment. Just copy the config file into a new machine and it's done.

Pro Has docker like system built in
Pro Allows parallel configurations for multiple projects
As everything is isolated, you can have on the same machine multiple configurations to meet project requirements that would be mutually exclusive on other OSes.
Cons
Con Based in China
Con Customization is a bit hidden
GUI is not straight forward for changing GTK+ or QT themes.
Con Deepin store apps not up to date
Con Cannot customize desktop environment
Because the developers have locked down desktop customization is A HUGE detractor against the idea of setting things up how you want.
Con Team doesn't know what to do
Deepin has changed the base 4 times, and the name 3 times. The Desktop Environment also has been changed 4 times.
Con Slow default repos
Download speed for packages from the default repos, is abnormally slow if you don't choose the correct sever.
Con There are issues restarting (on a PC)
Con Pretty laggy
Con Strange development organization
There aren't any sort of improvements over Deepin v15.1. The only changes are icons - they've become better.
Con Very slow installer
Because the servers are in China.
Con Installer lacks features
Con The configuration language is hard to figure out
For good reason. It's a purely functional language. However not even close to bash.
