I can't stand hamburger UI, giant title bars and that annoying menu/title bar at the top so I never "upgraded" to GNOME. It seems to me that GNOME team took a bunch of macOS features and stitched together a DE. However, while macOS is quite logical and there's a reason why things are on that OS, much of how GNOME works makes little sense from usability point of view.
This is why I stuck with Xfce, Unity and Cinnamon. I run all three of these DEs on my various computers and laptops.
But now that Ubuntu is moving to GNOME, what's the point of using Ubuntu over Fedora? RedHat has all the GNOME devs and they have the best GNOME + Wayland implementation. And that implementation actually works without Xorg. Other distros that run GNOME still can't get Wayland working right. Can Canonical/Ubuntu team make a better version of GNOME than RedHat? Given the history, I'm willing to bet money against that.
I'm also quite sick of apt-get and inflexible PPAs and managing them has been an absolute hell. Things just break, packages end up conflicting and untangling the mess can take you hours. I find Fedora's DNF and Copr a lot more sane (almost as sane as pacman and AUR on Arch but probably not as good).
So in conclusion, I really don't see a point in using Ubuntu anymore. If you want APT, just use Debian instead. If you care about GNOME, use Fedora. I'll be replacing Ubuntu with Fedora on one of my laptops later this year... and not with next version of Ubuntu+GNOME.
