IMO the best backup is a combination of things. Definitely use either My Phone or PIM backup.

To restore anything else use Sashimi. While not really a back up program it can restore all of your custom registry setting, install all of your software, register it, set up your email and exchange accounts and more. There is a bit of a learning curve but but its worth it. Sprite is a great program if you want a traditional backup program but I no longer use it.
