ELI5: if I were to fly around the world, would I get there faster by flying against the rotation of the Earth, or would it be the same?

Your absolute speed would be greater when flying with the rotation of the earth. But your speed relative to the surface of the earth would stay the same because the medium you're flying through, the atmosphere is rotating with the earth. 

Either direction you go, you will be traveling through the atmosphere at the same speed.
