Ubuntu is a very bad example of a linux distro.
Sure Arch users need to raise their hand and scream they use Arch and that the code is vanilla and they run GNOME with all it's bugs... do you remember how when Ubuntu went back to GNOME the Canonical developers fixed GNOMe's bugs, yes a distro actually fixing bugs upstream and not just packaging shit, some would prefer that instead of pretending the memory leaks are the fault of the user.
I used many distro including Arch, SUSE,Debian(and Sidux),Fedora, Mandriva and for years I am stuck with Kubuntu LTS because it works and I don't need latest library co compile latest XYZ program. I use this Kubuntu machine for my work so I can't and also I don't get any plesurre from rolling updates and fixing broken stuff or fighting with new bugs(I know how to work around existing ones)
Manjaro/Archlinux as really good about not having anything 'extra' which helps reduce the cognitive load even if they require more command line skills. i.e I'd rather have to know 10 complicated things than 10,000 easy things.
Ubuntu is just constantly doing their own thing and is really bloated. Like Snap does the same thing as Flatpak but is Ubuntu specific (at least by usage) which pretty much defeats the point of having portable packages.
