Rengar or kha'zix

I play both, and both are fun, but i find K6 to be more fun and rewarding. I heavily recommend getting a lot of practice with him; he's not easy to learn how to play well.

Deff Kha'zix. By far my favorite jungler to play, and he is FUN AF.

probably khazix first, as i find him less feast or famine, he has more escape options and you can still spam W when behind to poke

I play both a decent amount. I feel kha has a higher skill cap, in regards to manipulating isolation, and knowing what matchups require what evolutions, in what order. Rango is high skill cap as well, but you will do better on him sooner than you will kha. First few times I played kha, he felt worthless to me.

I have more fun with Rengo because I always feel like I am not doing dmg on Kha even with an isolated Passive aa>Q>Tiamat combo. The resets are nice but I find Rengo more fun to play and easier to farm/fight early on.

Khazix is easier, with a better payout. <-( main.)

Kha Zix is way more fun, while Rengar is more of a pro tryhard champ (not hard to play as though . - . )

Neither

get kha'zix, I have a 65% winrate with rengar and trust me, he is not worth learning. If I could go back in time and main another champion I would.

He is clunky after the bola changes, he has a shit ton of bugs, RNG kill potential because of crit, etc...

Also he is harder to play than kha'zix yet not as rewarding when mastered

As I rengar main... i recommend khazix so you don't shame us by playing rengar badly for the first time :3
