It depends on your needs and workflow. Personally I spend most of my time on my laptop in the terminal, browser, email and one or two other apps like Discord. I just want something that is simple and stays out of my way and I don't want to spend my time crafting the perfect desktop. Stock Fedora+Gnome with a couple extensions pretty much covers all my needs.
Other users have different expectations and needs and perhaps KDE suits them better, and maybe they are happy spending hours fine-tuning their desktop experience. All good and I'm happy we all get to have a choice.
