In dBFT the attack vector is a collusion attack between elected delegates. In practice I do not see this being any more likely than a 51% hashpower attack.

However most delegated systems are still young. The only reason people believe that 51% attacks are impossible is because it has worked for 10 years. If delegated systems work for the same amount of time, I don't see why they wont get the same reputation.

I think Dan Larimer gives a good argument on the situation.

Edit: His Conclusion is something many people should consider, when outright rejecting delegated consensus.
