I'd say that before CBM both are good filmmakers(giving Nolan a slight edge in critical acclaim but Fav better at making $).
Money doesn't always mean that the movie is going, otherwise FF would bomb. And Zathura was a lackluster, which tried to cope Jumanji IMO.
Besides, I would advice you to check out all Fav's movies' avarage ratings on RT

And by the way, Favreau didn't direct Swingers.
