I think Oda is going to find a way to make both characters look good in the fight, so I'm guessing Shanks is going to have the upper hand and is going to hit Kid with some advanced conqueror's attacks. And similarly to how Luffy figured out how to use advanced conquerors haki by getting hit by Kaido's attacks Kid will do the same thing here, and the cliffhanger of the fight will probably be Shanks and Kid splitting the sky at the end or in the middle of the chapter.
That way Kid is going to look good by being able to pull off the sky splitting feat, and Shanks will look good by having the upper hand through most of the fight and also eventually winning the fight in a future chapter.
