When comparing Solus vs Nix os , the Slant community recommends Nix os for most people. In the question“What is the best Linux distro for the most up-to-date packages?” Nix os is ranked 8th while Solus is ranked 14th. 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.
Ranked in these QuestionsQuestion Ranking
Pro Rolling release
Which means you don't have to suffer from version to version updates that can break it.
Pro Easy installation
The installation procedure for this distribution is quite simple. It's GUI based and all you have to do is to follow the instructions given by the installation window itself.
Pro Modern desktop environment
The default desktop environment used by Solus is called Budgie and is quite nice and minimalistic.
The system itself is very stable. All packages in the repository seem to be carefully picked, well prepared and run stable.
System boots quickly and stays responsive. Does what operating system should do, and does it really well.
Pro Most stable Rolling Release Distro
Pro Exclusively for desktop systems
Pro Great package management
The software center makes it really easy to install the latest software through Snappy and Flatpak. Including third party software.
Pro Rock-solid Distro
Very stable and well curated.
Pro Lightning fast boot time
Pro Seamless packages
It may not have the most obscure packages, but the packages it does have is a good number of everything a Linux user needs. Gamers, developers, desktop users, etc. all have the necessary packages and then some. The packages themselves are integrated perfectly and are very well updated.
Pro Default experience is clean and easy
The default desktop experience on the Budgie version is very clean and streamlined. Although the Budgie DE isn't the most customisable, but it's customisable enough for me to recreate the desktop style of ElementaryOS with the dock and bar at the top.
Pro Friendly towards proprietary codecs, firmware and drivers
So you won't have to enable PPAs or extra repos for that.
Pro Well curated software
The software is well curated in the repos, you have access to flatpaks and snaps, so virtually, all the software you'll ever need is there for you.
Pro Friendly community
The only community who values the newcomers. Very helpful community.
Pro Built from scratch
Pro Great for Haskell development
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.

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.
Pro Extremely reproducible state of installation
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 Versatile snapshot system
You can use and test snapshots without rebooting. Booting into snapshots or test configurations is possible without risking the system's stability.
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.
Con Not much software
There is not much software available.
Con Lack of software in repositories
There is a lack of software in the repositories. This is the only OS where I have had to build some applications from source or install from the app's site within the first month os usage. Though this is most likely because the distro is still relatively new.
Con There is often a black screen after update
Con An upgrade breaks the system quite often
Con Forums are not very friendly
Con No USB Image writer
Con The default desktop environment is not very customizable
Maybe because it's a relatively new project still in its infancy and this may be fixed in the future, but Budgie is not very customizable. You can only change the theme and wallpaper.
Con Slow development
Con Software a bit slower to launch than for other distributions
Con The configuration language is hard to figure out
For good reason. It's a purely functional language. However not even close to bash.
