Google sync will restore apps that fine.
But what is the value of titanium?
The value of titanium is the ability to restore the data in those apps. Over time you build up data in apps. This data can be levels in angry birds, login info for words with friends, passwords in password box, settings in WiFi tether, tasks in Tasker, settings in a live wallpaper app, playlists in a music app, and on and on and on. Yes google restores the apps for you but it can take time to get all that data back. This is where TB comes in. One click restore of all apps, apps and data, system data, or everything.
And yes it can save the desktop settings but your widgets will probably need to be re-added.
