I’m not familiar with sway or hyprland, but KDE automatically finds and configures any modern scanner and printer in the network, makes all programs use the same theme, saves my passwords and certificates, auto-mounts attached drives, auto-starts programs and services, handles which program opens which file type, has a nice workspace overview, lets me configure the firewall, grub, bootsplash screen, VPN, network settings, monitors, keyboard layout, etc… all with sane defaults out of the box, localized to my language, and easy GUI configuration.
