It is just to get newer versions of the proprietary drivers faster, and to have a more similar environment as developers. (Like if a feature of the driver is dependent on a new API just added to nearly most recent kernel)

Kernel updates can bring better support for different hardware which as well can influence how well the GPU drivers work, like, improving them.

😇but nice to hear that it works on your machine well 💪🏻💪🏻💪🏻

Don't know about your hardware. I don't own a notebook anymore. I read good things about the AUR package optimus-manager-qt for hybrid GPUs (iGPU+dedicated GPUs) but also that it can be a bit tricky.

I exlusively used dedicated Nvidia cards in desktop rigs with Arch & EndeavourOS since 2017 when I switched from Win 10. Additionally exclusively KDE.

Though I had a bit of experience with other distros and desktop environments before my switch I'd wager to say you should give one last try to EndeavourOS, even if you have barely any Linux experience. I mean you had so many failed attempts. One more won't hurt.

Use EndeavourOS not arch. First, it uses the standard initial graphical system-setup (Calamares), then it comes with some good default settings & tools and finally a welcome screen which features links to additional tools like mirror selection (for faster updates), update shortcuts, package search, docs/wikis/forums or logs.

I'd select KDE in Calamares and I'd install the graphical package manager octopi via "yay octopi" after system installation and activate yay for the AUR in the octopi settings as e.g. optimus-manager-qt (which you should only use with hybrid GPUs) is only available in the AUR. You need to click the alien symbol in octopi to install from the AUR.

The AUR (Arch User Repository) is the repository for packages not available in the main repositories. AUR packages are user contributed where the maintainers write a so called PKGBUILD file which contains the steps to build and install a package from foreign sources (e.g. from a debian DPKG or from github sources). With octopi you can quickly open the PKGBUILD file and look from where the maintainer pulls the parts of the package.

The amount of software available in the AUR is gigantic but it can potentially contain malware (which happened a very few times). But you'll have a hard time finding users who actually had that happen to them. A good indicator that the package is ok are its number of votes. But if you really want to know you have to check the sources in the PKGBUILD. If they come from github, you could check the github-repo and only it's stars (votes) if you won't read the sourcecode.

That all sounds mighty complicated but it isn't. Just try to install packages from the main repo. Click the alien symbol only when you don't find something official.

So with octopi and the welcome screen you don't need to enter any terminal commands for package installation or the system update. I had only a few updates where problems occurred in like 7 years and they were always fixable. The Arch Wiki and the Endeavour forums could always help.

I can't guarantee you'll have a better experience than with the other distros and you will meet some bumps or roadblocks for sure. I'm not playing the the most current games and a lot of retro games via Lutris and Heroic. For some of them I had to tinker a bit and try different starters than Steam. Arma, Path of Exile, Sekiro (fitgirl repack), Diablo Immortal were tricky but all the steam games or e.g. Witcher 3 via Heroic run very nice.

On the screen where you login (usually SDDM) you can switch between Wayland and X11. Which are two very different Display managers. Wayland is the replacement for the very old X11. It works way(land) better with AMD GPUs than with Nvidia which are usable though but work much better on X11. Games can be faster on wayland for Nvidia than on X11. But things like missing color management in nvidia-settings make me stay with X11.
