>>2206575OpenSUSE Leap is the official cost-free version of commercial SUSE Linux Enterprise Desktop distribution (SLED). As of Leap 15.3 users receive the same security & feature updates as SUSE's paying enterprise customers do & at the same time. It has a strong branding and is one of the oldest actively maintained distros.
Leap is a highly optimised distro with good performance metrics. This is due SLED being meant for professionals that do e.g. audio work, graphic design, 3D modelling, CAD/CAM, and such. This benefits users of OpenSUSE Leap in such a way that it's a very good platform for gaming & multimedia. Ubuntu (and Mint as a derivative of Ubuntu) tend to have performance issues & memory consumption problems on desktop.
Notable distro specific feature of OpenSUSE is YaST. It allows you to make deep system configuration changes from GUI without a need to touch CLI. In other distros you do have to actually know how to use multiple separate CLI/GUI utils to perform config tasks and have knowledge of how to edit plain-text config files in /etc directory but with YaST you can use single GUI to perform most of these changes.
YaST can also be used to perform system upgrades, install software, partition disks & more. It enables use of OBS (Open Build Service) & one-click-install of software through a web interface.
It provides users with vanilla versions of KDE Plasma and Gnome.
Here is also couple reasons why not use OpenSUSE:
OpenSUSE defaults to BTRFS file system which is a piss poor attempt at cloning some features of ZFS. Ubuntu offers the actual ZFS support out-of-box. However use of either is not adviced for desktop users whom should use ext4. Ubuntu & Mint default to ext4.
YaST has a tendency to restrict you from making "stupid" decisions over how to admin your own system. This restricts the very freedoms that you'd choose to use Linux for. But new users might want this "safe-guard" which is why I tend to suggest OpenSUSE for new users.
