I currently use pop-os which is an Ubuntu derivative. I use it because it works well, is easy, and it's smoother than Ubuntu. My second choice would be Kubuntu if I wanted to commit to KDE. My reasons are that I'm doing important business on all my computers and I don't want to spend a lot of time trying to troubleshoot things that don't work. So I stick to the LTS releases nowadays.

A downside of my approach is that it's less customizable, not as up to date and slightly constraining.

Over the years I have used a lot of different distributions. I've had many success and even more failures.

So many people have strong feelings about their favorite distros. The big differences are about ease of installation and configuration, stability, open source vs. proprietary code, community support and ability to customize. Other than that, they are all basically Linux.

Arch is not for the faint of heart but it is awesome if you can get it installed. And they have a great support community. There are a lot of Arch variants that are easier to install.
