So like I’ve tried kde plasma a bit not much tho I mainly wanna have a dual boot setup where for office and some light games I use windows but sometimes i will use onlyoffice on Linux as well so I really want a distro which Is stable gives me control over stuff like kde like I can do cool stuff and costomization but I want it to be stable not get a lot of updates that can break stuff if the updates don’t break stuff and are frequent I’ll still call it stable I’ll mainly browse in firejail for my work because those unmaintained govt sites have game a gazillion viruses at this point so in a nutshell i want a stable os in which I can do some cool customization and I have control over it and maybe play some games which support linux and have it as a dual boot and also primarily use it for business purposes
Fedora is good. I personally run Arch—very vanilla, but may require some knowledge to install. Also, I don’t dual boot, which makes things easier. So, yeah: Fedora, or a derivative distro like Bazzite is probably your best bet.
You can try distribution here : Testez les distributions Linux en ligne - DistroSea

For KDE plasma, you have :Kubuntu, Opensuse (leap version is the stable), Manjaro (based on Arch).
the best stable distro for the plasma desktop is kubuntu LTS (currently on plasma 5).
the upgrade to plasma 6 is coming in April, but plasma 5 works VERY well and i plan to keep using it until i see how things settle out for the 26.04 release.
the upgrade path is a GUI button on the so you are in total control of when that takes place.
the other option is to install kubuntu 25.10 now with plasma 6 and upgrade to 26.04 as soon as it’s released.

fedora is semi-rolling and changes can come at any time if you accept them.
from what i gather, the best practice for stability on fedora is to install one version older than the current release (so you have 6 months of bug fixes ahead of you), and then watch the updates carefully for anything that might impact your workflow so you can hold those updates back until you are ready… but i’ve never used fedora, so no idea how well that works.
Late reply, but maybe someone will find it helpful.
I also find KDE Plasma to be the best, if not the only usable, DE for Linux and better UX than Windows or macOS. I’ve gone through this last year, spent a lot of time testing various distros.
Here:
I’m still mostly on Windows 11, so this is written from a perspective of a Windows user who want to switch to Linux some time….
I came to few conclusions.
I really like Debian for its legendary stability and I’m also mostly familiar with Debian side of the Linux universe because I ran Debian servers for years. However, it comes with way too old version of Plasma and to get the latest version, the one that currently comes with other distros, I’d have to wait… two years.
Problem is that older/early versions of Plasma 6.* had bugs that got fixed in later updates (those I’d have to wait two years for), and the latest updates got some nice improvements (new bugs too, but, oh well…) so you really want the latest Plasma updates. But if you don’t mind the older Plasma and you care about stability then you can’t go wrong with Debian. Caveat: if you have NVIDIA GPU then, nope, look elsewhere.
I also dislike derivative distros for various reasons (that are beyond the scope of this thread) and I prefer to stay with a main core distro as I feel this is more future proof and a better choice from support perspective. So this leaves pretty much Fedora KDE as the only reasonable choice for me for running KDE Plasma. It is somewhat less stable than Debian but it also offers better support for NVIDIA GPUs than Debian, has a large and very active community and works closely with KDE team. The only thing that bothers me is Fedora’s ties to Red Hat.
Despite being a derivative of Debian, Ubuntu is a very stable and one of the largest, most mature and best supported distros out there (there is unmatched wealth of documentation for Ubuntu on the web) and so Kubuntu would also make a decent choice for running KDE if you can overlook Canonical’s shenanigans and don’t mind Snaps. This would be my second choice, I’d just have to shake off my dislike for Snaps.
Arch is out because I don’t want to spend most of my time tinkering with my OS. CachyOS is nice but has issues that discouraged me and it’s way too overhyped. If you want peace of mind and stability then stay away from anything Arch. Arch something I might run on a secondary PC to tinker with in my spare time but not as my main desktop.
So considering all, I agree with @skyfishgoo that Kubuntu is the best choice at the time for the OP taking into account their requirements:
Large, mature and well supported distro
Great software compatibility (you may still come across apps that only work on Ubuntu)
GUI driver manager (for installing NVIDIA drivers)
Stable, based on Debian
Fairly recent Plasma updates (only few months behind Fedora)
Most likely, I’m gonna end up on Fedora, use its for a while see what happens and Kubuntu will be my plan B. For now, I’m delaying the switch for various reasons, but it seems dumping Windows will be inevitable at some point.
