Switched for Unity for a few years when I was erring on Ubuntu side, where I like the minimalism style.
Gnome 3 was a shock but nothing any normal human being can easily overcome. The hardest was to live without a taskbar, but I'm free now.
Would never touch KDE-let-s-make-this-pixel-also-clickable, but that's the power of freedom: you can choose what you like.
Nothing is forcing you, but you may be surprised.
Do you use NetworkManager or systemd-networkd or something else? What is your login manager? Do you use Gnome for email or anything else?
I am asking this in earnest because I don't believe Gnome has left anything useful beyond GTK as the library (if you consider that useful) and maybe nautilus. Everything else is just bolted on and weird and broken.
