Best linux distro 2021 RHEL vs Debian based
The best linux distribution of 2021 is not easy to decide. First choice is if you prefer a Linux distro that is RHEL based or Debian based.
For a Linux server or a Linux desktop the requirements are quite different. There is no best linux distro really. Most of the established Linux distributions are great to use.
Put the names of most known Linux distros. in a hat. Pick one, that’s the best distro for 2021 and 2022. Jokes aside, you should choose what you are even slightly used to.
RHEL based Linux distributions
If you goal is to use Linux in a professional environment – at work that is. RHEL based distros. will make you familiar to the Linux enterprise environment and things will be much more familiar on Red Hat Enterprise Linux (RHEL) once You used a similar OS.
Linux distro for server
For a server, you want to choose a distro that is well known and stable. Good reputation is very important. Tested packages before release is much more important. Long support and updated and running without crashing are basic requirements for a Linux server.
Red Hat Enterprise Linux – RHEL
The OS that many Linux distros. are based on is a top-tier enterprise Linux distro. With top support, security updates for critical operations. This one is not free but Red Hat have a developer subscription licensing program that allows for 16 production RHEL instances for free. More about RHEL Developer subscription here.
Centos 8 / Centos Stream
Centos 8 and Centos Stream have caused some controversy recently. Centos 7 was a downstream release distro. Updates were released on Centos 6 and 7 after they were released on RHEL 6 or 7. Now Centos 8 is upstream compared to RHEL 8. This means, updates are sent to Centos first then to RHEL. That places Centos after Fedora and before RHEL in the updates flow making Centos a testing step before RHEL instead of using fully tested packages.
With all the problems Centos 8 and Centos Stream is still a great Linux server distro to consider. Centos is free.

Alma Linux & Rocky Linux
Since the Centos 8 announcement, people have been looking for a new RHEL based distro that is downstream from RHEL. For this, these new distros. where recently created basically rebranding RHEL sources and adding their own to make a new distro.
I’ve tried Rocky Linux and the setup was the same as Centos 8.
Oracle Linux 8
Oracle is a huge company known mostly for Oracle Database and Java but I won’t go into details there. The Oracle Linux 8 is binary compatible with RHEL 8 and Many things are the same as in the Red Hat distro but they mention their kernel is unbreakable as part of the name. They have paid support available for Oracle Linux 8 but the base version is free.

Debian is one of the main well known GNU/Linux distribution. It is completely open source. It’s one of the oldest Linux operating systems.

SliTaz is a light-weight linux distribution ideal for a portable OS on a USB flash drive. It will work with older hardware and the size is very small.
Try any of these or any other distros you might want to look at. For server would I choose Centos 8 and for Desktop Fedora but that’s my preference. You might like Arch more or Ubntu or even Oracle Linux.
You can always try another distribution later.
