Yes it would be more impactful. In Whitebeard's case it was Whitebeard and the Marine HQ having direct war. And after Whitebeard died, Blackbeard caught up pretty quickly, even obtaining Whitebeard's power.
Here however we have the worst generation, which directly invades the new world, causes an all out war and dethrones 2 Yonko which ruled for decades, in their own territory. Especially since Wano itself has ties with a lot of secrets regarding the WG itself too. This has much wider implications for the story hence.
