i still prefer plasma over gnome, but my sorta controversial opinion on the matter is that gnome 3 was way better than gnome 2. gnome 2 was boring, ugly, using it felt like a chore and frankly not much simpler than kde at the time. gnome 3 tried to create something new and unique and i have huge respect of them for that. it was also much, much more pleasant to use than its predecessor. but it still isn't better than plasma. the only time in my opinion that gnome was a preferable option to kde was during the early kde 4 dark ages, which was a necessary transition, but it was terrible regardless
tl;dr gnome >=3 still isn't better than plasma, but it was a step in the right direction bc gnome 2 was way worse
