I've heard many different things regarding PwnageTool, QuickPwn, and the speed of the resulting device. What is your opinion on this?

I ask because I'm kinda willing to wait for QuickPwn (mostly because I've restored thrice in the last month switching between 3.0 B4 -> 3.0 B5 -> 2.2.1 -> 3.0 B5 -> 2.2.1 -> 3.0 GM -> 3.0 Final), but I know the PwnageTool jailbreak is sitting right over there in my downloads folder... (thanks SB ).
