Vlingo or speaktoit? Anyhow, both are better than siri?

Nowadays iPhone is boasting about siri app of their phone. What we can say is that siri is just a updated version of android's vlingo and speaktoit assistant. Both are better in its own way. In vlingo it has many sub option so that when a user is to ask any topic, he can choose the category (only if he want). In speaktoit assistant, it is like the messaging window, with the phone's background. Also, in speaktoit, the replies are like an answer from a 2D avatar, which is customizable. I use both vlingo and speaktoit, and like speaktoit a little more.
