Gnome extensions can look pretty much exactly like kde or better depending on your taste, kde is easier to customize and more intuitive. I like that gnome is extension based with each extension being something you pick, many having their own customization and settings.

Some extensions I like: Arcmenu: start menu like windows, kde, etc. lots of layout options, replaces the hot corner big icon search menu thing

Dash to dock: use on handheld, perfect touchscreen menu customizable or (use one at a time) Dash to panel: use on desktop, even more customizable, basically gives you a panel since gnome by default has the hot corner android like app menu (which I also use mostly on the handheld, love the hot corner for moving stuff around)

Windows thumbnails (pip any window, monitor downloads or chats)

I use a lot more but forget the names, nothing really breaks if you toggle use incompatible addons or whatever it’s called. You can also edit the addon and change the version since that is what the devs do 90% of the time to update it.
