Vettel was only a tenth behind Webber despite the lack of KERS and on average KERS gives you about 0.3-0.5s a lap, so there's little doubt Vettel would have taken pole were it not for the KERS issue, especially with the way he has trounced Webber in qualifying for all of 2013 until Suzuka. Had it been the other way round I bet rotten tomatoes would be hurled at Vettel... oh wait they already are, since Vettel can do no right while Webber can do no wrong in the eyes of many so-called F1 fans >_>
Vettel wins (again), but it's a lot less straightforward... I don't know how anyone can still deny his abilities (Unless they're that delusional) but he basically did a Prost with all that strategic battling, I believe an article on F1Fanatic will give an in-depth explanation to this. Not to mention he did a Senna in Singapore and probably a lot of other races, if he has any flaws with his driving then I don't see it given that he could possess the characteristics of 2 drivers rated so highly but for different reasons.
But that aside, the star of Suzuka was Grosjean, the way both Red Bulls were sleeping at the start made it easier but he capitalized on that to hang on to the lead for as long as possible, and the fact that Alonso in 4th was over 30 seconds behind is a testament to his impressive driving, he might have even been able to hold off Webber for 2nd were it not for the lapped cars considering that he was doing just fine for 6 laps. A pity he denied a Red Bull showdown for the lead but we can't fault him for that since he was merely doing his job. He has come a long way from his crash-prone days, losing Raikkonen may not be such a big issue for Lotus after all. If the Big 4 were taken, my choice of drivers would definitely be Hulkenberg and either Grosjean/Button/Rosberg if based solely on skill.
