My daily driver is an nvidia laptop with opensuse, takes like one afternoon to get everything ready with barely any former Linux experience.

Just use zypper (or yast) to add the proprietary nvidia repository (or nouveau) and install your drivers. Install everything else you need through zypper (or yast or flatpak). Familiarise yourself with keybinds, set new keybinds (not needed of course but its nice to know keybinds - if you’re using KDE already they’ll probably be the same anyway). Select KDE’s dark “breeze for OpenSUSE” theme (or some other theme, but breeze for opensuse just is so polished). Configure other preferences (night light from sundown to sunrise, set up Firefox sync (if you use that), connect to onedrive or whichever cloud you’re using, … . Done. No need to wait :)
