i think plot wise Orochi getting killed by Zoro will bring more character development to Zoro considering we might have a full flashback of him because of Shimotsuki Bloodline and because he had connection with Yasuie which is he died because of Orochi.
But Zoro vs King is just a power-level plot wise, but if King had a connection with Shimotsuki which is some people assumed he killed Shimotsuki Ushimaru in Ringo, that would be a good way why Zoro vs King happen.

If you included Orochi as an option you are basically just trolling tbh
