I found this article from the Autosport magazine.

This year promises to offer us further perspective on how the pre-eminent talents of Raikkonen and Alonso stack up to each other - and as of Melbourne, even taking into account the performance advantage of Raikkonen's car, Kimi's driving looked on a higher level than Alonso's.
Interestingly, there are engineers at McLaren, with the data in front of them, adamant that they still haven't seen from Alonso the sort of devastating high-speed precision that they used to routinely get from Raikkonen.
You get the feeling that they're still waiting for that 'wow' moment, when they realise their man really is something special, whereas the Ferrari guys probably got to see it for the first time with Raikkonen last weekend.

Also some engineers who worked with both Senna and Raikkonen reckon that Raikkonen may even be faster than the great Ayrton.
