For the longevity of a product and intuitive design. But it is a matter of opinion, and if you are more comfortable with Windows, then stay with Windows.
We use it for every linux service we need to have running. It really works great and is easily manageable with the SUSE Manager, which helps a lot with the updating process. Although it is not stressfull on the CMD itself, it really does simplify things. Besides that, we are really happy with working with SUSE Linux Enterprise Server.
The support window for service packs after a new SP is released is too short.
Community engagement is low.
There are times when supported packages fall too far behind and create compatibility issues with applications. The Open Build Service usually provides a way around this, though.
We've been using this OS for about 8 years in a productive environment. During this time, we have never run into any problems that stopped or impacted our production environment. We have been able to solve any problem we ran into using either common sense, suse documentation or suse support.
Support personnel are helpful and fairly fast to bring resolution to non-emergency issues. Patches are created and posted in a timely fashion. We so far have not had any major problems that needed support
macOS just makes sense to me. Each OS has its pros and cons.. macOS works for me. It's well designed, intuitive, and efficient. But it's not cheap... well, macOS is basically free, but you need the hardware to run it, and the hardware isn't cheap. Pick the right tool for the job and for you. And even though macOS may not be thought of in an enterprise environment, it works remarkably well if configured properly. Tools like DEP and ABM from Apple enable device management and lock them to the company. Use an MDM like Jamf to push policies and packages. Jamf can also manage accounts and authentication. JumpCloud is another great product for account management. Although it might not be all included in the box, with the right knowledge, you can build a robust and versatile enterprise Mac infrastructure. You can even do zero-touch deployment in most cases with the correct setup. And Apple employs engineers to help you get it set up right.
We went straight to SLES when we initially started migrating oracle to hana since at that time, HANA came on a pre-installed server that had to be purchased from an official vendor, and SLES was the only allowed OS. We stuck with SLES after we became certified to do our own installations because so far, SLES was a good fit for us.
