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.
Theme: depends. I'm rocking Gnome on my laptop, so something like Otis looks good in it. Kripton or Jasper (what I typically use in XFCE) also look nice regardless of DE IMO. Just depends, but mostly, it's a dark theme so my already meh eyes are spared a flashbang. Very original, I know.
Icons: Gruvbox Plus. Dunno, just always kinda feel it. Guess I like the designs? Also love me some Win10Sur and Reversal Icons.
Cursor: Bibata, typically. Oreo Cursors, if i feel like adding more pazazz and color...which is most of the time, honestly (also helps make my mouse easy to find. Not that my desktop is cluttered it's just nice to immededly know where it's at with a glance).
