Ac1dsn0w is a jailbreak program developed by a team of hackers that uses the limera1n exploit to jailbreak and tethered jailbreak our devices. In the beginning, the program contained Apple's proprietary code, but its developers modified it and now it only includes code made by them and theoretically cannot be attacked by the company in any court. To see how effective is the new method of jailbreaking and tethered boot on our iDevices, a user he made the above video in which he demonstrates how quickly both redsn0w and Ac1dsn0w make a tethered boot.
redsn0w comes out a little ahead in terms of speed, but it comes out a lot ahead in terms of functionality because it offers us a whole series of options that Ac1dsn0w doesn't have. If you want more reasons not to use Ac1dsn0w, the video clip above should be convincing.
