Reading the comparison table you linked, there is a misleading point, but I may understand it wrong: they claim that CT "does [...] avoid the need for the client to trust a third party", but in reality the client still needs to trust CAs, and have the CA keys in his trust store. Removing a CA key from the trust store of the browser basically invalidates all certs signed by that CA (just like it is now). It's just a framework for monitoring the released certificates. Trust on the CA still needs to be there. And as Moxie sad: "Whenever someone is proposing an other authenticity system, the question that we should all ask is: who do we have to trust, and for how long? And if the answer is: a prescribed set of people, forever, proceed with caution."

With CT we still have to trust CAs. Basically forever.
