I'm of the belief all the Worst Generation will confront Kaido and Linlin, so Drake should attempt to go up. As it stands, though, he has no choice but to stay and fight as the island is floating over the sea, so escape is impossible. The live floor is mostly under control. Especially if Marco stays behind to keep King and Queen at bay. Taking out Kaido, who's the source of the problem, is the best course for survival.
