Ubuntu vs OpenSUSE
The clearest difference between these two is the desktop: Ubuntu ships GNOME 51, OpenSUSE ships KDE Plasma. Underneath, Ubuntu pairs APT with DEB and OpenSUSE pairs ZYpp with RPM, and the two have very different amounts of recent data behind their package tables. Ubuntu 26.10 also asks for 6 GB of memory against 2 GB, and its releases are the more recent of the two.

What differs
Base & packages
Ubuntu 26.10 records GCC 16.2, glibc 2.44 and LibreOffice 26.8.1 on APT with DEB packages. OpenSUSE's full package snapshot in the dataset is older: release 42.3 records GCC 7.1.0, glibc 2.22, LibreOffice 5.3.3 and systemd 228 on ZYpp with RPM, while the 15.2 release from 3 June 2021 records kernel 5.3.18. The gap between those snapshots is why versions should be read from each card rather than assumed.
Desktop & display
Ubuntu defaults to GNOME 51 and has removed the X11 session in 26.10. OpenSUSE defaults to KDE Plasma, recorded at 5.8.7 in the 42.3 snapshot, and it too records Wayland as the default display stack.
Release model
Both are versioned. Ubuntu's newest dates are 20 July 2026 and 15 October 2026. OpenSUSE's newest recorded release date is 1 October 2025, with full snapshots for 15.2 on 3 June 2021 and 42.3 on 26 July 2017, plus 42.2 on 16 November 2016.
Hardware requirements
OpenSUSE lists 2 GB of memory and a 4,328 MB image; Ubuntu lists 6 GB and 6,309 MB. Both figures are recorded for the defaults of each distribution, not for minimal installations.
Init & immutability
systemd on both, at 261 for Ubuntu and 228 in OpenSUSE's 42.3 snapshot, and neither is immutable. OpenSUSE adds YaST2 and AutoYaST for installation and administration, where Ubuntu relies on its own installer and configuration files.
Verdict
Choose Ubuntu if you want GNOME on a recent base, the newest kernel in the data, and the broader ecosystem of guides written against DEB packages. Choose OpenSUSE if KDE Plasma is your desktop of choice, if you want a graphical administration tool covering installation and configuration, or if 2 GB of memory is the constraint. Note that OpenSUSE's package table here is older, so check the card before comparing specific versions.
FAQ
Which one uses KDE Plasma?
OpenSUSE, recorded as KDE Plasma with 5.8.7 in the 42.3 snapshot. Ubuntu records GNOME 51 in 26.10.
Are the package versions comparable?
Only within their own snapshots. Ubuntu's are from 26.10; OpenSUSE's full table is from 42.3, with 15.2 recorded separately at kernel 5.3.18, so a direct version comparison would mislead.
