My only issue with alt-tab is when I have more than one window open for a particular program. I then have to use the arrow keys to select the right window.
If you install gnome-shell-extentions-alternate-tab this will revert alt-tab to the old behaviour, without the need to vertically switch when you have more than one instance of an application.
