Should i buy Rengar or Vi?

Vingar

Vi. Rengar is still getting the kinks worked out of him. As is Vi but more so Rengar.

Vi, she can jungle and actually the jungle is too easy for her.

Rengar nice dmg and nice skill but riot kill ulti rengar with this stupid delay 3 sec....

Vi. She can scream through the jungle and can perform solid ganks... as long as you get good with her Q. Misuse your Q and you can get yourself into situation you can't get out of.

Well tbh I like Rengar I think hes better imo.
