This is an honest question, not trying to get into an argument...

Why not use the default provided then and take the defaults as opinionated? That's what I do actually. I might change very few options, but I generally use the defaults. It's not that you have to configure kde before it becomes usable, the defaults are pretty ok.
This is only true if complexity under the hood actually affects your default experience. I don't think it's the case for KDE. "The chance" is indeed higher, except in GNOME it seems the bugs are actually real.
