I was a big Unity fan (the old window manager for Ubuntu). And 17.04 came a long and threw it out due to community pressure it seems, and replaced it with Gnome.
At that moment, I wasn’t so happy. My memory of Gnome desktop was from when it really sucked. However, I am really pleased to become a new Gnome convert. The desktop is pretty clean and fast, and the customisation options with things like Gnome Tweak and Gnome Extensions means that I can pretty much have the desktop I want…. awesome…
