Against Oven and Daifuku's giant genie, Sanji didn't even use Diable Jambe and his speed feats remain pretty impressive. I don't really see how he looked disappointing in context.
Sanji wouldn't be where he is if he wasn't as passionate as he is. He's acknowledged the help he got from Germa and was even willing to use the Raid Suit to help others but he chose his emotions over strength and things turned out fine in the end. I don't see the point in discrediting all his efforts as simply due to his dad's help.
Not to mention, he was only given the Raid Suit after saving his family which was a choice he made due to his kindness so it's a matter of his generosity helping him in the end. Plus his bros have germa enhancements and Raid suits but they'll never accomplish what Sanji has and will accomplish. He also honed his armament haki to withstand increased temperatures and that's not due to Judge.
