My opinion is, that Kid always uses hard or complicated tricks that takes time for Conan to solve. Even if Conan did solve it, Kid always have a back up plan such as in chapter 634. Kid's plan was solved by Conan but then, Kid used his back up plan to escape. Its not that I am supporting Kaito kid but he is not that bad. He actually saved George's live and Kid never steal. He always returns the things he took. His aim was only to compete with Conan.
