I'd definitely prefer Kubica over Massa as world champion. I'd like to say that I'd be happy whoever won the title, because the driver that ends up with the most points deserves it, but that isn't the case this season. For me to see Kubica as the correct world champion he'd have to beat Hamilton by at least the four points that were stolen from him at Spa. If he manages that then fair play to him, he's been great this entire season. Massa is a cheat and a trash talker and doesn't deserve the championship even if he finishes 6 points ahead of Lewis.
I'd see Kubica as the correct world champion if he won by only one point, because his driving has been far superior to Lewis and, given equal equipment, would've trounced him with this year's performance. Neither of the two drivers likely to win this year's championship actually deserve it. They haven't driven well-enough to do so.
Edit: Just something from Autosport that cheered me up today.
BMW in final push to help Kubica

Robert Kubica
BMW Sauber have assured Robert Kubica that they will do all they can to win the world championship this year, after the Pole's second place in Japan put him back in title contention.
Kubica had been 20 points adrift of Lewis Hamilton heading into the Japanese Grand Prix, but the troubles suffered by the McLaren driver and Ferrari allowed Kubica to close the gap down to 12 points.
With two races to go, Kubica has urged his team not to let their surprise opportunity slip from their grasp.
And BMW Sauber technical director Willy Rampf has made it clear that the team will make every effort they can to deliver what he wants.
"As long as there is theoretically still a chance to win the world championship, then we will not sleep," explained Rampf. "We'll try and do what's possible in this short space of time."
Although there is no testing between now and the end of the season, and no major updates planned for the F1.08, Rampf believes progress can be made in the way the team approach races.
"We'll try to really concentrate on every detail of the preparation for these races. There won't be any big updates, but we can make small changes, and we can try to use the potential of the tyres in a more perfect way."
Any steps to improve the speed of the BMW Sauber will be vital, with Renault having come on so strong in recent races - and Rampf suspecting the R28 may now be quicker than their car.
"In Singapore, they (Renault) had good pace but they benefited from the race situation. Here, they were strong throughout the weekend, and slightly stronger than us. We'll try to fight back in the last two races."
When asked if he was surprised BMW Sauber were in the position they are in, Rampf said: "I can't say we expected to be so close to the leading teams at two races before the end of the season. It's overall very nice"
I think we may see Kubica use at least one aggressive fuel strategy in the final races and hope that Heidfeld can help. They could always send him out on a qualifying lap with his tyres on fire to get him on the second row alongside Robert. But seriously, unfortunately I don't think there's anything much that BMW Sauber could do to their car to help Heidfeld warm up the tyres now. Shame, really. 
Yes, he is fast, almost rock solid and much more down to earth that Lewis or Massa. If he was given Ferrari/McLaren quality car this season, he'd be way in front of both of them in standings.
Plus, he is as ugly as Prost, so that has to be another champion quality

You can have it in any colour - as long as it's black. Or red. Or blue. Or green. Or white. Or navy blue. Or...
