Totally agree with this. Except, I've never liked the KDE look and feel. It's like the worst glossy cartoon ui ever. Yuk. To be fair, I haven't looked at it recently, so the gloss might have been toned down or removed.
But to your point of bug fixing, I absolutely agree. macOS is plagued by this as well, but mot to the degree Linux DE's are.
I've used multiple desktops since the 90's and loved it. macOS has had support for a while, but the animation switching from desktop to desktop was horrendous. I got a utility to fix that, but it's a joke they don't just include a checkbox to toggle the animations. This is one huge UX fail in my mind.
KDE's changed its look, but more importantly, it's not set in stone: it's entirely possible to change its settings and theme. It's the most configurable DE out there.
I really wonder sometimes why distros don't use it more, and make their own custom themes for it, instead of just leaving it at the default. It wouldn't take that much work to make themes to make it look almost like anything you want. Or you could even make a different version of Plasma which emulates some other OS/DE if you needed to, leaving all the underpinnings intact.
