Gnome 43For most purposes, though, I find that I increasingly don't care about 1 or 2 years of difference in the base OS. Most of the toolchain is stable and well established. There are only a small handful of things I want to pin to a specific version (like node.js or Python), but these can usually be installed side by side with default packages. If not, I can always install it in a container. :)
Ubuntu probably do the HWE kernel better than stable backports kernel, the HWE kernel has a release schedule.
There's been more community support for Ubuntu in the form of PPAs but Flatpak has mostly solved that problem for the things I care about.
As such, I've already switched all my laptops to Debian, and will switch my desktop and work computer when I can be bothered.
For a while the Debian kernel packages had -ckt suffix (Canonical Kernel Team), although it doesn't seem to be the case any more.
