Let’s be honest, the rankings of gnome-look are weird at best and there is no good resource to gauge what icons / cursors / themes people like to use in their everyday DE.
So please share what icon-pack / cursor theme / GTK|QT theme you use, and why.
I used to be really into theming. But now, the default Breeze and Adwaita look good enough that I haven't bothered wanting to change them in a couple years.
That and thmes always appeared to be some degree of "broken" that I just don't bother anymore.
I do always change the cursor to the black Adwaita one, even on KDE. It just feels right to me.
When I did still use themes, Numix, Arc Dark, and whatever "flat" themes that I could find were my favorites.
