So the color coordination for haki is very helpful for clarification. I remember seeing at least more haki clashes in the manga, but I think there is only one shown in the anime. The most interesting point is that Whitebeard can use his earthquake "energy" to completely negate one of Oden's biggest attack (I think the only other all out attack shown is the clash of blades in the title screenshot).
The action feels like it was expanded on, but I don't think they really added anything from the manga. It wasn't the best animation team, but the animation and artwork were great throughout the episode.
Another great addition was expanding on Marco. I think it's funny how both Marco and Oden end up being the annoying but highly loved children of the family.
Hopefully we get expansion of it in the next episode, but it seemed like Oden has some sort of kenbunshoku activation to see Toki being in trouble. Just based on the script, it is described as a Sanji-like "maiden in distress sensor", but the visual when he lets go of the chain is different mechanics.
Overall, definitely a great episode, and was fun to see the younger versions of the Whitebeard execs.
