The issue is that everyone needs at least one or two customisations that they can't live without, even though they don't need all of them. And so they end up installing gnome tweaks which is a buggy mess which will never be fixed, as with most third party extensions.
In comparison, even though there are a lot of bugs in KDE, they will eventually be fixed, given that most customisations are first party.
I, unfortunately, have a limited amount of time and prefer not waiting for those bugs to eventually be resolved. So I prefer using Gnome, where the limited flexibility is not a problem for me, and the far more consistent and stable Gnome environment is extremely valuable!
So I use Gnome.
That's the great part about Linux.
And I can somehow manage to do that without suggesting that KDE developers need to stop treating their users like a bunch of kids with no jobs living in their mother's basements.
Many in the Linux community seem incapable of doing that second thing, which is the crappy part about Linux.
