If you "just" wanna do the PIM information then PIM backup is the fastest, BUT it seems to cause issues with text messages, upon a restore.

If you wanna do a system wide backup, then I suggest Sprite Backup. That has worked great for me. Sprite backup will do PIM only, as well, but is a bit slow because it insists on rebooting your phone, to do the backup, then a reboot again, when it's done, no matter how much/what you are backing up.
