I'm planning to move from Windows 10 to Linux on a 13-year-old desktop with 16 GB of RAM, a 1 TB hard drive, an Intel Core i3 processor, and integrated Intel HD Graphics. I tested Linux Mint in a live environment and it felt surprisingly responsive, 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 Snap packages being pushed on me. However, LMDE uses Cinnamon, and Cinnamon felt less smooth than XFCE in my testing. I also like the appearance and Windows-like layout of KDE Plasma, so I'm wondering whether installing Debian with KDE would be a good alternative.
My priorities are a responsive system, a helpful community, good security, long-term stability rather than a rolling release, and a setup that works well without extensive troubleshooting. I mainly use the computer for browsing, office work, VS Code, watching videos, storing photos and videos, and occasional light gaming through GBA emulators.
Would KDE Plasma run smoothly on this hardware, or would XFCE be a safer choice? Is LMDE preferable to regular Mint, and would Debian with KDE be a sensible option? I'd also appreciate recommendations for other stable distributions that offer KDE without being based on Ubuntu.

LMDE sounds like a strong match if you want Debian underneath while keeping Mint’s straightforward setup and documentation. It offers a stable, secure, low-maintenance environment and should satisfy your preference for avoiding Ubuntu-specific choices. Cinnamon is somewhat heavier than XFCE, though, so the live-session performance difference you noticed is worth taking seriously.
The best choice mostly comes down to how much desktop polish versus minimal resource use you want. Mint XFCE is likely to provide the smoothest experience and the easiest transition, while LMDE gives you Debian’s base with Mint’s simpler, more integrated experience. Plain Debian with KDE gives you more direct control and the KDE desktop you prefer, but installation and troubleshooting may require a little more hands-on work.
For a conservative setup, Debian Stable with KDE or XFCE are both reasonable. KDE should not be rejected because of its security-update reputation; the main practical difference is that Debian Stable may ship older software than faster-moving distributions. Testing each desktop from a live USB is the most reliable way to judge whether KDE feels responsive on your particular hard drive and graphics hardware.
For ordinary desktop work, Debian with KDE Plasma should be perfectly usable on those specifications, especially with 16 GB of RAM and integrated Intel graphics. KDE is not an unsuitable or neglected desktop on Debian; it receives security fixes through Debian’s normal package and security processes. XFCE will generally use fewer resources and may feel snappier on an old hard drive, but KDE can still work well and may feel more familiar coming from Windows.
If you were doing modern gaming, newer software and graphics drivers might matter more, but browsing, office applications, VS Code, media playback, and lightweight emulation should not require a rolling-release distribution.

That’s reassuring. I mainly use the machine for browsing, office work, VS Code, videos, and photo and video storage, with only occasional GBA emulation. KDE’s interface appeals to me more than Cinnamon, so Debian with KDE is becoming more attractive.
