User blog comment:Rimo13/Rengar and Khazix! Who's the strongest and the most op of these two?!/@comment-5219125-20121019160528

Rengar is a bit easier to use at higher levels because he is a bit more durable, but at lower levels, Kha'zix is much easier to snowball, especially when you are aware of your opponents positions.

I have always had an easier time playing rengar, but he might become more difficult than Kha'zix after this recent nerf.
