Redsnow, ultrasnow, snowbreeze? What's the diference?

[Shlov1]

OK, so all the unthethered jailbreak solutions have come out today (THANK YOU THANK YOU THANK YOU). But my question is what is the difference between reddsnow, ultrasnow and snowbreeze? I am running windows so which should I use. I only need to JB and not unlock. What is the difference of all the different versions?

Redsn0w-jailbreak
Ultrasn0w-unlock for some old basebands
snowbreeze-custom ipsw creator for windows
Pwnagetool-custom ipsw creator for mac

Custom ipsw allows for baseband retention for unlockers, you can make the ipsw pre jailbroken, even include cydia packages ready to go.
