Even Luffy and Law were controlled by Doflamingo's strings, Sanji didn't had a clue of anything Doffy was capable to do and made him use one of his strongest moves "Overheat", something that Law didn't managed to using his abilities to the higher extent. Zoro using Daisen Sekai against Pica show that he put some effort into it, unfortunately Pica was almost inoffensive, passing the whole arc trying to kill fodder and not accomplishing anything, and yes, Zoro needed help to fly cuz he can't fly, i think thats a standard since ever. But see it however you want to see, you can't complain that Sanji has no feats
