I'm happy enough to call it the best driver lineup at the moment. Think about it.
Ferrari have two demonstrably WDC competitive drivers. I know you all hate Seb and he can be flaky but he wins races regularly, poles regularly and has 4 WDCs and you wouldn't actually be surprised if he won the WDC if Ferrari got the car right would you?. Matching Seb last year showed Charles' ability is up there with all the top drivers too.
No other team can really say that they have this across both drivers.
Lewis is best of them all, but Bottas is there as a wingman and everyone knows it.
Max is stellar, definitely a match for the Ferrari boys but Albon is completey unproven and is being used as a second and in a training role.
Daniel has as much potential as anyone but Ocon is unproven and is there to see if he can be good.
Carlos has the potential IMHO but noone is going to suggest he is better than the Ferrari drivers, and Lando is still in 'Promising' territory.
So yes, they can claim to have the two best drivers in F1.
