SYLAS VS UDYR - WHO IS A BETTER MAIN

Sylas - is a bruiser with pretty DeCenT amount of damage. He can cast any ult of enemy team champ even earlier than the champ, whos ult was stolen. Pretty good at jg and (actually) any lane. Superstrong at late. But can be easily ganked in early game.

Udyr is the coolest druid in the jungle. Ultimate ganks and pretty tanky, when SmaRt.

But who of them is the strongest?

I understand that situations in game can be different, but the thing is I cant decide which champ to main.

I want to be useful for my team as jungler or bruiser, not support or heal.

I thought a lot about this, but i think that there are players which have more experience in this game.
