who is your opinion is the top 3 champions for jungling and why?

1.
2.
3.

While I don't play them, my fav 3 to see on my team are Maokai, Udyr, and Lee Sin... They al have good clear times, can counter jungle, and all have solid pre 6 ganks.

1. Lee sin
2. Nocturne
3. Nautilus

Lee Sin's ganks are great all around, but he doesn't scale well into late game.
Nocturne's level 6 ganks are absurd. Wards mean very little for this guy.
Nautilus is a CC bundle pack. His clear time is slow till about level 4, but 1 or 2 ganks later and this man is to be feared.

1. Lee Sin
2. Noc.
3. Alistar/Amumu

1: Shyvanna
2: Amumu
3: Lee Sin

Shyvanna clears super fast, and does insane damage throughout the game
Amumu has a painful first clear, but once he's out of the jungle, he has amazing ganks
Lee Sin was already explained

1. Olaf
2. Maokai
3. Lee Sin
This is only imo

1, Udyr - For his great sustain with his Turtle stance, and his AOE pheonix stance, Also, he can gank with his stun.
2, Lee sin - His ganking potential is fantastic. He throws down his Q and then E and can easily score a kill/assist.
3, AD Kassadin - Now i know you may think i'm trolling, but im not. I've played AD Kassadin jungler before, it's actually very fun and he can be very powerful. Also he has a silence and his ult which makes him be able to gank easier,
