I don't think Sanji will kick any major arse this arc, which is a bit dissapointing. However I do beleive we've seen hints that Sanji is definitely able to take on High Level Mooks like Oven or even Cracker.

1. his fight with Judge was only lost becasue he didn't expect his father to use his soldiers in the manner he did.

2. While Escaping Cacao Island with the cake he was so fast Oven didn't realise what happened.

3. His blocking The Genie beofre it could hit Carrot.

Theirs probably more, but I can't remember them at the moment. I definitely think that without their Raid Suits Sanji's siblings would be weaker than him. Also I'm fully expecting Big Mom to turn up during the kaido arc wanting to ally with the Straw Hats so she can get more of Sanji's cooking. If I'm wrong meh.
