Linux

it's a lot of work to switch distributions, and I don't recommend unless you have a really good reason!

kde is supported on Ubuntu... id suggest installing it and trying it out first. the bugs u state sound like desktop environment issues and not distribution bugs ...

I am not entirely sure what I am hoping from this post, but maybe a "yea, it is worth it" would ease my mind a bit.

If that is all you need, I'll throw you a "yea, it is worth it". I have been running Fedora with KDE Plasma as my main personal desktop on multiple machines for five years or so. Mainly desktop/laptop, but I even used it pretty regularly on a tablet for a while (I stopped simply because I stopped using the device altogether due to preferring having the full keyboard of a laptop) and even use it on my HTPC. There may be a better HTPC OS, but I am just so used to it everywhere else that it seemed simple enough to get going and I just stuck with it.

You're looking for stability and KDE Plasma. Fedora doesn't seem to be the right candidate.
Arch Linux (or Endeavour / Manjaro), or OpenSUSE are better candidate.

I don't use laptops.

I have some dell optiplex and poweredge in the home-lab.

These machines are ported through a KVM, and I'm using a desktop on proxmox where the GPU, mouse, keyboard, sound and cam are ported into the fedora VM via proxmox from there the KVM connects.

I play WoW and zero-k, but the voice chat isn't working in WoW.

Fedora is solid. It’s as close to Debian as a fast update track distro can be in terms of stability.

It’s also obnoxious. Between SElinux, updates typically requiring reboots, cockpit being a sloppy feature incomplete mess, and things just taking longer to do on fedora than anything other distro, you might want to think twice.

It’s not bad, it just makes certain trades not everyone is happy with. It feels windowsy. You use fedora because there’s a reason you are using fedora. It’s not a default distro.

Fedora is pretty stable itself, but I have experienced some problems with KDE, for instance dolphin crashing on opening a directory attached by KDE Connect. Keyboard shortcuts seem to work just fine, but they may be not configured the way you expect, so consider tweaking them in the settings, no difficulties here.

Also, keep in mind KDE is quite a heavy environment, it may feel slow after Xfce, even on a middle-end system. Personally, I would probably choose GNOME if I returned to the past moment of installing Fedora.

Fedora is based on Red Hat, you'll need time to get used to some minor differencies in contrast to Ubuntu, especially commands' syntax. You'll have to reinstall all needed programs, relogin your accounts and so on. I think you will generally be able to copy and paste some configs, but they may need a bit of adjustment.

While it is quite stable, Fedora still recieves updates really frequently, you should ask yourself if you really want to update every week or two.

If you use Xfce with X11, be ready to face Wayland's specifics with screen recording and working with monitors.

My conclusion: KDE is probably not an optimal choice, but switching to Fedora is worth it, if you are ready to spend a day or two getting known with it's specifics.

Fedora is very stable until a kernel update breaks a hardware function.

I moved from Linux Mint to Fedora KDE about a year ago. Haven't had a single complaint on either my laptop or desktop.
