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.

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.
