What are some mechanically simple junglers to play?

I decided I want to get to G4 or higher in every role. I just got my Support account to G4 so now it’s time to learn jungle!

I want to focus on macro because I know that’s much more important than mechanics, so I need some junglers who are very mechanically-forgiving. Which champs do you recommend? Bonus points if they’re also quite supporty!
