I think George has a good season in him, whether he has it next year is a different question, he certainly has questions to answer after last year so I'd agree to an extent there, but he is still a contender in the right car IMO.
Carlos I will respectfully disagree as I think he has continued to get better each season and I don't think there is much between the drivers on points as you mention. I won't argue who would win it, just that Carlos is a contender.
Oscar I think is very strong, but until he can manage those tyres he won't unlock all of his potential. His one lap pace almost being on a Par with Lando now, who is traditionally a very good qualifier.
But in any case, next year it is almost impossible to predict how the cars will perform and it has the potential to be either another walk in the park for max, or one of the most exciting seasons for quite a while.
