I am in the same boat. Windows 95 like desktops are simply not the most optimal way to work anymore.
The reason I like gnome most is because it is so out of the way. I am enjoying maximal screen estate while switching apps is just as easy as it is supposed to be.
When gnome shell was new some things were buggy, especially on low power machines, but that changed really quick. I can't think of a single issue.
Different strokes for different folks but I don't enjoy the OS/2, Windows, KDE way of doing things.
I'm thankful we have choices.
