KDE Neon (https://neon.kde.org/) is pretty great. It's based off the latest LTS version of Ubuntu, but is less bloated and gets KDE Frameworks updates quicker than Kubuntu.

Do they support older LTS releases? Like for example, do they still support Ubuntu 16.04 or Ubuntu 18.04?

I'm asking because if I install 20.04 now, I may want to continue using it until its EOL.

I can't say my "day-to-day machine", because that is (unfortunately) windows 10 - due to my day job. However, after work, i spend nearly as many hours on my personal machine which is linux...and that machine runs Fedora 32 for the last several months (I recently switched over from 2 or so years of Linux Mint usage). When i started with Fedora 32 i started running KDE (and KDE is typically not a choice i tend to make for my DE)...Mind you, i had not run KDE for almost a decade because it used to be too heavy and slow to run for whatever old machines that i used as my personal laptops. But lately, KDE seems to be lighter...i won't go as far to say as light as, say, xfce (and to be fair i have not conducted any fair test between xfce and kde); but KDE nowadays is certainly way better than it used to be.

My primary environment has been KDE on Fedora for the last 20 years or so.

Wow, great! I have used Fedora for little less than a year some years ago, but then I wasn't happy with having to upgrade distros every 6 months.

I don't upgrade with every version. Usually I do it on odd numbered releases. Sometimes I'll make an exception for something I really need but typically I don't have any issues at all with that approach.

How is fedora on kde

I use the KDE spin when I'm doing a fresh install. I find it to be very good. I tend to tweak my desktop a bit, I don't run with the straight defaults. The software for searching and installing packages seemed to not work well last time I checked but that was years ago- I tend to do all that with the dnf cli.

I have not moved to Wayland yet and it is not the default so that will be a big shift at some point. I also avoid nvidia. I used to use their cards but just got tired of the constant hassle.

I don't really try to push anyone towards Fedora or KDE. There are a lot of great choices when it comes to Linux but for me it's always been good. I run MacOS on my MBP for the few applications I can't run on Linux but that list has become really short. At this point I think Webex is the last thing that's holding me there. My next laptop may be a Lenovo.

I have been using Manjaro KDE for several months now on my daily driver, I must say I like them both.

Main issues was finding few packages with a different name than the one used on Debian based distros.

I didn't make many changes on KDE since I'm not a huge fan of customization, it's fast and has a really good look by default, same things I love of few distros shipping with GNOME such as PopOS.

I've been using Plasma on NixOS, switched from GNOME 3 because I was having terrible issues with the Nvidia drivers (it may have since been fixed). It's fine although I kinda miss gedit and the GNOME terminal emulator.

I'm using KDE on KUbuntu on my work laptop day-to-day for the last 18 months.

But I've been using it for longer than that as I do recall using it for half of my university too. I recall I was using MATE before switching.

Fedora. After using Ubuntu (KDE Neon since it came out) since basically 4.10 I'm really liking it!

I use openSUSE tumbleweed with Plasma and the experience is really great.
