He adoptado el ecosistema Debian supongo que por casualidad, ya que en su momento tuve que instalar en un micro servidor HP un sistema operativo, y elegí OpenMediaVault porque, con un funcionamiento ágil, me ofrecía lo que necesitaba. Y al adentrarme en GNU/Linux para escritorio, en las distros derivadas de Debian me quedé. Y como en cuestión de entornos gráfico KDE es mi preferido, en la actualidad mis preferencias son: Tuxedo OS, Quark OS y Kubuntu, ya que además me brindan una instalación de controladores propietarios de nVidia fácil.
Preferiría derivadas de Debian lo más alejadas posible de Canonical. Pero no siempre es posible tenerlo todo. Aconsejo Quark OS sin reservas.
I have adopted the Debian ecosystem I guess by chance, since at the time I had to install an operating system on an HP micro server, and I chose OpenMediaVault because, with agile operation, it offered me what I needed. And as I went into GNU/Linux for desktop, in the derived distros of Debian I stayed. And as in terms of KDE graphical environments is my favorite, currently my preferences are: Tuxedo OS, Quark OS and Kubuntu, since they also give me an easy installation of proprietary nVidia controllers.
I would prefer Debian derivatives as far away from Canonical as possible. But it is not always possible to have everything. I recommend Quark OS without reservation.

Hats off to the Q4OS team!
I originally stumbled upon Q4OS Plasma while searching for a ultra-lightweight daily driver for a relative's laptop with just 4GB of RAM. It blew me away with how smoothly and efficiently it ran right out of the box.
That led me to try their Ubuntu-based sister project, QuarkOS Plasma, on my own laptop. It gives you all the hardware support of Ubuntu, but completely stripped of Snaps and unnecessary clutter.
While I appreciate what Linux Mint tries to do, Cinnamon always felt a bit heavy and bloated with preinstalled apps for my taste. QuarkOS solves this completely through their Desktop Profiler, letting you choose between a minimal, basic, or full desktop right from the start. Add in the guaranteed 5-year security updates, and it's easily one of the most efficient, user-centric distros out there.
I love this distro, its the fastest fork of Kubuntu 26.04 without forced snaps but still want snaps on demand. And its lighter since its less Ubuntu forced telemetry.
Also I just really want a plasma 6.6 version and other distro is yet to have it (ex. Sparky, MX, Tuxedo). I am so amazed on my workflow with all the updated features of plasma 6.6 as its now my baseline desktop that I require myself I shd have no lower than 6.6 as it has bugs that disrupts my daily use case.
Kinda confused the team is the same with Q4OS but this distro QuarkOS has no website like them.
