This might be just a matter of what I've gotten used to, but I have the "Activities" view (which shows previews of open windows, as well as the dock-like thing for launching applications) bound to the super/windows key which is nearly always very easily accessible.

If I'm switching windows and I'm not alt-tabbing, I usually just hit the super key and select the window from the thumbnails/previews.

I don't find that to be unproductive, but then, I haven't really been even trying to change the basics of my desktop or experimenting much in a while, so it might be that I've just settled for it to some extent.

If I had to first move the mouse to one location in order to get a list of windows, and then again to another location to select the window I want, I don't think that would work at all. But with a very easily accessible keyboard shortcut for the first part it does.
