I just love the unusual shape and the aesthetic overall. Using it with Nova and a very dense layout - I can barely see my wallpaper, but I like it that way.
Got used to these so much, phones with "normal" shaped icons look weird to me now :)
I love Borealis and Arcticons (Light/Dark/You) as there is a broad selection of app coverage (even some more local apps to the Netherlands) and I just like the simplicity of the icon packs
One of my favorites is Umbra. I like the vivid clean circles, and it has wide compatability, working smoothly with Nova Launcher, but also working well with Samsung OneUI 5.1 (which many icon packs only partially work with). https://play.google.com/store/apps/details?id=com.ryanmkelly.me.umbra
I'm using the Nothing icon set bought it because I also have the Nothing phone 1. It suits the phone obviously but it lacks so many games and things, I couldn't really recommend it at this point I put in icon requests months ago and have seen no difference at all.
Best I can do at an uploaded image as I haven't figured lemmy out yet https://ibb.co/j4PxyFF
I was using Fluent Icon Pack but it doesn't seem to have been updated in a long time.
The past two years I'm using stock OneUI icons and launcher and occasionally change it to Niagara Launcher.
I've used so many over the years, but have stuck with Viral the last couple of years. It's a very comprehensive icon set and I like the dark-ish theme.
