Ranked in these QuestionsQuestion Ranking
Pro Rolling release
Pro Modern desktop environment
The default desktop environment used by Solus is called Budgie and is quite nice and minimalistic.
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 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.
System boots quickly and stays responsive. Does what operating system should do, and does it really well.
The system itself is very stable. All packages in the repository seem to be carefully picked, well prepared and run stable.
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 Most stable Rolling Release Distro
Pro Built from scratch
Pro Greatly favours stability over anything else
CentOS favours stability over being up-to date. For this reason it ships with packages that may be up to two years behind in order to ensure stability over everything else.
Using older versions for packages means that they have been thoroughly tested and used in production for quite some time, and are ensured to play well with each-other.
This strategy has paid off quite a lot in the past. One example is the Heartbleed bug which left CentOS unaffected since it was using a two-year old OpenSSL library which did not have the bug.
Pro Applications don't have to take into account potentially breaking changes in libraries
Since CentOS backports all updates and bug fixes to older versions in order to maintain package compatibility across releases, applications hosted on Red Hat Linux don't have to worry about potential breaking changes in libraries they use, especially language libraries.
Pro Built-in support for containers
Comes with built-in management tools for containers (Atomic CLI, Cockpit) and a container runtime in the form of Docker engine.
Pro Built-in disaster recovery solutions through clusters
CentOS has several built-in solutions for disaster recovery. For example, it comes with pacemaker which can be configured to manage multi-site and and stretch clusters across multiple geographical locations for disaster recovery and scalability. It can also be configured to trigger notifications when the status of a managed cluster changes by using enhanced pacemaker alerts.
Con Slow development
Con Software a bit slower to launch than for other distributions
Con Forums are not very friendly
Con There is often a black screen after update
Con An upgrade breaks the system quite often
Con Not much software
There is not much software available.
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.
