I'm preparing to move from Windows 10 to Linux on a roughly 13-year-old desktop with 16 GB of RAM, a 1 TB hard drive, an older Core i3 processor, and integrated Intel graphics. I tested Linux Mint from a live USB, and it felt noticeably faster than my current system, so I'm considering the XFCE edition.
I'm also interested in Linux Mint Debian Edition because I prefer Debian's approach over Ubuntu's, particularly because I don't want to rely on Snap packages. However, I'm not especially fond of Cinnamon, and I like the look and Windows-like workflow of KDE Plasma. I'm wondering whether installing Debian directly with KDE would be a better choice.
My priorities are good performance on older hardware, a helpful support community, strong security, stability rather than a rolling release, and a system that works well without extensive troubleshooting. My typical usage is browsing, office work, VS Code, watching videos, organizing photos and videos, and occasional light gaming through Game Boy Advance emulators.
Would KDE Plasma run smoothly on this hardware, or would XFCE be a safer choice? Is Linux Mint Debian Edition preferable to regular Mint, even though both would generally mean using Cinnamon? Would Debian with KDE be a reliable combination, and how does its security and maintenance compare with XFCE or GNOME? Are there other stable KDE-based distributions worth considering?

You could also look at stable KDE options such as Debian itself, openSUSE Leap, or a Debian-based distribution that offers Plasma directly. Fedora KDE is well supported but has newer packages and a shorter release cycle, so it may not match your preference for a conservative system. Whichever distribution you choose, test Wi-Fi, audio, video playback, suspend, and external devices from a live USB before installing. For the least hassle, Debian Stable with KDE or XFCE is a sensible starting point.
Debian Stable with KDE Plasma is a perfectly valid combination. KDE is not a second-class desktop on Debian, and security updates are provided for the packages included in the supported release. Debian’s KDE version may not have the newest features because the distribution prioritizes stability, but that is consistent with what you want. Install only the software you need, keep the system updated, and use Debian’s official repositories for the simplest maintenance experience.
Your hardware should run KDE Plasma, especially with 16 GB of RAM and integrated Intel graphics. The older CPU and mechanical hard drive are more likely to affect responsiveness than the desktop environment itself. KDE has more visual effects and background services than XFCE, but you can disable animations and compositing if needed. XFCE will generally feel lighter, while KDE may feel more familiar and polished coming from Windows. The best choice is whichever feels better in a live session, preferably after testing from an installed system as well.
For your workload, Debian KDE should be fine. Browsing, office applications, VS Code, media playback, and older emulators do not require a cutting-edge distribution. If you want something lighter, Debian XFCE or LXQt would leave more resources available, but the difference may be modest with 16 GB of RAM. Replacing the hard drive with an SSD would probably produce a much larger improvement than changing from KDE to XFCE.
Linux Mint Debian Edition is a reasonable, stable option and combines Debian’s base with Mint’s relatively simple setup and tools. However, it does not necessarily make Cinnamon lighter than the regular Mint edition; the desktop environment is still the main factor. If Cinnamon already feels sluggish or simply isn’t appealing, LMDE may not solve that problem. Debian with XFCE, LXQt, or KDE would give you more flexibility.
