I totally agree it's not for the average user but I'm not an average user. That's why I like it so much. I love the way I can make my computer work the way I want it, rather than being stuck with someone else's design decisions and having to adapt to them (I really hate opinionated design). My KDE is customized heavily though I never needed to use addons because it's so configurable.
I really like this about KDE. And the number of options isn't in the way. When I'm thinking of something new to do there's usually an option for just that that I'd never seen before. I love software like that that feels way ahead of me, almost anticipating my wishes.
Gnome on the other hand, their developers have this attitude of "you shouldn't want to do this". I don't like software or other people telling me what to do. I'm sure their stuff is based on UI principles but those are made for the masses too. I only care about what works for me.
But yeah I'm a power user, that's not for everyone. I love that KDE exists though. And it's great that you like gnome, that's the power of Linux/FOSS.
The only thing I object to is when people claim Linux should get one standard UI (and then they usually want that to be gnome). That's not ok for me. But it's also impossible to enforce anyway.
