Others have mentioned the shortcomings already, but the real question is why do you want to switch to debian? If there's a particular reason you wanna switch go for it, maybe dual boot first to see how it goes.
Linux
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You will get the same version of Plasma and probably older versions of some other packages you use. With 5.27 being the last significant update until Plasma 6, you’re good on that for a while. Nothing will be newer than what you already have. None of your packages will get any updates beyond bug fixes and security updates, but it will be rock solid.
Kubuntu is also reliable and has newer packages. Personally, I don’t think there’s much to gain here unless you’re set on something that doesn’t have snap and don’t mind running older versions of most packages.
Why not?
Install Debian, get a stable base on KDE Plasma 5.27 LTS while KDE 6 sorts itself out, and for everything that you need up to date (browsers, office, etc) just install the Flatpak version from Flathub.
I'm also running Kubuntu, but I'll switch to EndeavourOS. I wouldn't pick Debian because I like having the latest versions of things as they're released, some things even in beta, but other than that I think it's a solid choice if it fits your needs.
I would suggest going straight Arch. EndeavourOS introduced a lot of weird things for me. The new Arch Installer is just text based but made everything so easy. Much happier now
I would second this. I’ve used Endeavour and it’s nice, but it doesn’t have much of a purpose. It’s an easy installer with some default packages. Once it’s installed, it’s 100% Arch but with a different name and you don’t know how some things work because they were automatically configured for you. Might as well use the real thing. The archinstall script is easy and you only have to do it once.
There is an axis I had not considered - the relative "uptodateness" of the packages. Debian is + for stability but - for "newfeatureness"
