Also, Pwnage Tool creates an image that you can always use to recover back to, should you need to, and still be jailbroken.

With Quickpwn, if you ever need to restore, you have to jailbreak again.

They each have their advantages, but most people prefer Quickpwn.
 
Pwnage takes much longer because you have to re sync everything to your phone, but it's a clean install.😱
