The antiglare screen is no joke
Whether you use Smartswitch or not Google does a backup anyway of settings, calls, SMS etc and will restore that (you get the option) on first boot and sign-in. All your installed apps are in the play store anyway and you can let those auto pulldown through the store, you'll get the option to do this too on initial sign-in and sync.
Smart Switch is the best way though, then just let Google do whatever it needs after. Some apps need to be manually restored like WhatsApp though, so do a Drive backup and restore.
