Flexible bruiser junglers (AD or AP) such as jarvan and zac are best because if you have a team that you need to carry you can build more damage (lizard, hydra etc on J4, MPen on zac) and if you have a reliable team that you just need to contribute utility to you can build full tank (golem, locket etc).
