When comparing Ubuntu MATE vs Red Hat Enterprise Linux, the Slant community recommends Red Hat Enterprise Linux for most people. In the question“What are the best Linux distros for businesses?” Red Hat Enterprise Linux is ranked 5th while Ubuntu MATE is ranked 10th. The most important reason people chose Red Hat Enterprise Linux is:
RHEL 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 RHEL unaffected since it was using a two-year old OpenSSL library which did not have the bug.
Ranked in these QuestionsQuestion Ranking
Pro Perfect for people who like Gnome 2
The goal of MATE is to maintain the look and feel of Gnome 2, while maintaining compatibility with Gnome 3. To that end, it has also forked and renamed many of Gnome's core applications. It benefits from the years of work and polish that have gone into the Gnome project.
Pro Simplicity of Gnome with the power of Ubuntu
Debian was good to use but has limited documentation and is difficult to pick up. Ubuntu MATE brings the ease of design and logic of the Gnome 2 style desktop so it's easy to get around coupled with the vast documentation, forums and ease of learning/using the Ubuntu system.
Pro Works great on old laptops
It does not have a lot of system requirements so it works pretty well even on older laptops.
Pro Highly configurable
Comes with an option to configure as Windows-like, Mac-like, Gnome-like, etc. in a single click. Wonderful to get you started without having to learn it all from scratch.
Pro Behaves like Ubuntu with Unity - after Ubuntu-Gnome transformation
No better place to continue Unity experience with Ubuntu (Left-side panel, HUD) and not as awkward as Gnome
Pro Greatly favours stability over anything else
RHEL 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 RHEL unaffected since it was using a two-year old OpenSSL library which did not have the bug.
Pro Rapid security updates
Pro Each version is supported for a really long time
Each released version of RHEL is supported for around ten years by Red Hat with constant bug fixes and security updates.
Pro Built-in disaster recovery solutions through clusters
RHEL 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.
Pro Applications don't have to take into account potentially breaking changes in libraries
Since RHEL 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 Best support as far as hardware goes
This distro is by far the one with the largest number of certified server-class hardware.
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.
There is absolutely no reason to install it, since it uses the same package repositories as Ubuntu and you can transform any Ubuntu install into a Ubuntu MATE install.
Con Not bleeding edge
Users who want the latest and greatest software would be happier using Arch Linux, Antergos or another rolling release distro. However, because Ubuntu MATE is based on Ubuntu, users still have access to a large repository of recent software.
Con You need to buy a license
RHEL is a commercial Linux distributions and it's rather expensive as well, the cheapest license costs $349.
