Vettel seems very much at home at the Scuderia. The car seems to be developing in his favor and the team seems pleased with his progress.

We never saw that with Alonzo. The car was never good enough and it seems Alonzo was incapable of any positive input. Note that McLaren is keeping Button as they try to develop the Honda nightmare. Why? Could it be that Fred is only good at driving and lacks the ability to assist in the development? I don't know, it's just an observation.

I guess the change to Ferrari explains Vettel's lack luster 2014 season at Red Bull.
His bags were packed and he (Vettel) was already gone.
Rumor has it, Vettel was buying a Ferrari for his father at the factory before the 2014 season started. Coincidence? maybeeeeee.
