Considering it used to look like this¹ it's no wonder why people (including me) were desperate to theme it. It took until the last two or so years for me to not care to do that because the default look and feel of gnome is now pretty good.

Still, I wished they offered some more adjustments rather than just a paltry selection of accent colors (you can't even select a specific color...)

I’m not the last to criticize (relatively, I respect the things I’ve got for free) Gnome but yes, aesthetically, I prefer Adwaita to macOS.
