@shapis I agree. I used Gnome for several years before switching to XFCE. Gnome feels like a great DE for people who do not do a lot of things on their computers. I normally have 5 or so workspaces and on each a dozen of apps open. Some apps are workspace-specific, some are available on all workspaces. You are right, multitasking when you do so much is a pain in Gnome. And I really really tried to like it.
Not to mention that you need a lot of extensions to make it useful.
Gnome does great in terms of animations and overall look, but not very practical and feels very non-customizable.
XFCE looks awful out of the box and the lack of animations is quite annoying. But you can make it look good - see our custom distro based on XFCE - TROMjaro. And if you give XFCE a try you will realize how sane it is. You can customize it a ton without being overwhelmed by thousands of options. You right click on panels and apps and you get sane options to move or tweak them.
As for workspaces I personally use them as "names" on the top bar and can switch between workspaces so fast, almost like tabs in a browser.
Not as fancy as Gnome, but boy this is really useful. And practical.
I've also added mouse gestures on my desktop via Easystroke so I can move windows on any workspace via these gestures. So easy.
So I'd say that Gnome looks fancy, and it is very cool for those who do not do a lot of work on their machines and have to switch between many work spaces and lots of apps. And I'd say XFCE is extremely underrated, perhaps because out of the box it looks terrible. Maybe try TROMjaro....see how it goes.
