RedSn0w jailbreaks and utilities are more "trustworthy" than Sn0wBreeze in my opinion. Smoother UI, easier user experience, and won't push you into a brickwall because of all the custom this custom that that Sn0wBreeze loves doing. If you're bricking your device, you're doing something wrong on your end. Plus, RedSn0w isn't updated for iOS 6 jailbreak on A5+ devices, so the iPad 2 won't work with it.
