Jambo pool is larger, with small slide. Kidani has long slide and elaborate water play area for kids. Personal preference is Jambo pool including because it has a lot of areas to find shade and Kidani does not.
However, if I were getting a 1 or 2BR, Kidani wins by a large margin. The rooms are much larger, have an extra bathroom, more closet space and , if dedicated 2BR, you get one large porch running the entire length of the room.
