What champion is the most fun for beginners?

Hello , I have been told that the beginner champions to play are Garen, Annie , miss fortune and so on.

I tried them out a few times but they are kinda boring, they are so simple. So i decided to try out the mister 200 years aphelios . -> I lost 10 consective games.

After watching esport matches i tried Azir and got obliterated.
