We love to praise linux constantly and tell everyone to change to it (they should) but what are your biggest annoyances ?
Mine would be, installing software (made even more complex by flatpaks being added, among the 5 other ways there already were to install software) and probably wifi power management issues.
Which distro? Chances are you can install KDE on it and then select the Plasma session next time you log in.
On Debian-based systems, the package you would want to install is probably task-kde-desktop. More info here: https://wiki.debian.org/KDE
yeah i aware I can install kde.
