Do you use Gnome or KDE Plasma?

I'm relatively new to the linux space, I was introduced by the steam deck which uses kde, and it's pretty similar to windows in terms of how it works so that's the DE i'd be leaning towards when I eventually switch. I've never used gnome so i'm not sure if it'd be worth using I guess?

So I'm just looking for some input from the community, do you use Gnome or Plasma, why do you use it, and what's kind of like a pros and cons kinda thing between the two?
