Shaco Or Kha’Zix?

I’ve tested out all the recommended AD champs everyone has recommended to me with my couple posts, and I can’t decide between these two champs? On one hand, I love both of their kits and the flexibility these champs bring to the table, but on the other hand I wonder if I am better off mastering one of them or playing both of them? I have a great feeling that when Udyr’s rework comes, I’m going to be loving that because of his character and kit. In the meantime, I want to get one or both of these champs in my pool depending on who is better overall.
