Absolutely love it! I've donated hundreds of dollars to the Gnome foundation.
I like that practically all of the OS functionality is behind either super+seach or the quick settings menu. I love how powerful the overview is, and all hidden behind a single key press. I like that asking "Is X possible?" is immediately answerable, and 95% of the time it's right in the first place I think to look. I like the trackpad gestures and workspaces on my laptop where I don't have multiple large screens. I like that it has very little need for system tray icons which are clunky, inconsistent, and ugly. (Ex: Discord can only be quit from it's tray icon... -_-)
I'm not a DE power user apparently, but I'm certainly not the mythical "lowest common denominator" that Gnome supposedly caters to either. I do a lot of programming in C/asm/, and write plenty of code involving lots of esoteric math. I don't have much use for Python for instance, but I don't think it's "dumbed down" either. :p
KDE (and Windows to a similar extent) always has way too much "stuff" it wants to show you, 90% of it I'll never use. Every window toolbar is chock full of icons, and so many actions trigger popups, notifications, or dialogs that have little purpose. It's all terribly distracting and annoying. Still, I've donated hundreds of dollars to KDE foundation as well since it's an important part of the Linux ecosystem. I don't use it, but that doesn't mean I hate it, and I see no reason why it shouldn't flourish too. Open Source is not a competition.
