I voted for Vettel because He has been solid with his car being worse than Ferrari for most of time, He isn't lucky as Alonso, Alonso won several points due to luck.
Career wise, I'd still rate Alonso the best of them all, with Vettel being slightly behind, Vettel is faster driver but still makes a little more mistakes than Alonso, but Vettel is a lot more inexperienced as well.
PS- Michael Schumacher's come back because of money has been very poor and very unlucky as well. The König needs to retire for sure, plus F1 nowadays with DRS/KERS suck.
