I'm starting to think Vettel's more complete package out of the four these days, (I added in Raikkonen, how can you not?).
People tend to say Hamilton's the fastest driver out there, Vettel's just up there aswell in my opinion, then come the race, he's not that bad compared to Alonso now is he? He's also seem to have reduced the myth of 'can't overtake' the past few years,
Alonso, not the best in qualifying, possibly the best in the race along with Raikkonen, has the consistency.
Hamilton, qualifying he's one of the best, race distance wise, he's not bad either, but I feel the other three have a slight margin over him, probably the boldest out of the four.
Raikkonen, like Alonso, not great in qualifying, I would possibly go along and say he's one of the best overtakers since his comeback, and has been very consistent.
They are all very evenly matched with having different attributes, two of them have past their primes, ones in his prime, and the other is yet to get there.
