I face the same specific issue. I started with the French (Canada) layout years ago but now Windows sets the default to Multilingual/CSA because it has been made the official one by the government a number of years ago.
So now everyone that got used the “old” one has to fiddle with keyboard settings every time they use a new Windows session/computer.
And it’s not exactly a breeze to switch, as Windows often keeps the multilingual one and switches back to it when you use a different application. Gotta make sure to delete the multilingual and leave only one layout. It’s a real annoyance.
I’ve been using MATE since Gnome 3. I really liked the simplicity of Gnome 2 and was unable to adapt to their “new” way so I switched to MATE and it just clicked. I tried Gnome 3 a few times again but I just can’t.
As for why MATE instead of XFCE or others? Because I already used and tried XFCE in the past and prefered Gnome 2’s look and feel. In fact, I have been going out of my way for years to keep every app using GTK2 and my favourite theme because I like how it looks and feel, and Gnome 3 and GTK3 broke this. So MATE it was. They switched to GTK3 too eventually but it gave my time to adjust.
My only “complaints” about it are the file manager Caja, and the way you can list windows, which both feel very basic. I would like those two to get better.
I try and use different DE from time to time, from Fluxbox to E17, but I just go back to MATE. My favorite DE of all time was E16 but it took waaay too long for E17 to be functional and I ended up keeping MATE.
