Egghead was actually not that good, visual wise in the manga, no good battle scenes too.
Anime completely carried it and make it look like the best arc post time skip ever by animation alone. They really enhanced Oda's original work by 100x
Kizaru vs G5 scenes
Zoro vs Lucci
Gorosei entrance
Giants
Bonney and Kuma.
The director and producer must have deep knowledge of the story and knows how to actually convey the elements that can't be drawn in manga.
So yea definitely Egghead got the better adaptation by far. Wano is already excepted to have lot of banger moments and scenes, that's the thing to consider
