Kha'zix or Hecarim

Hi! So this is my first post on this forum. I am currently in Bronze 2 and I main Jungle. I find with the new jungle, it is hard to be useful late game. I own a lot of junglers and I enjoy playing Jarvan, Vi, Rek'sai, Rengar, and Nidalee. I am nearing 6300 IP and am thinking of getting either Kha'zix or Hecarim. If you could pls tell me who is better in Bronze in terms of early game ganks, late game scaling and who can carry harder. Also who you think suits my playstyle given the champs I listed and who is more fun. Thx :)
