The better ganks were an example.
Kindred is a late-game carry, Malphite isn't even a fucking jungler don't pull that shit, Maokai has extremely good ganks, tanks, and initiation, Nunu has godlike counter-jungling and specifically counters lee, one of your listed "op" champs, Fiddle is weak but has an easy clear with sustain, Jax is a late-game carry/split pusher, Amumu is basically the same as maokai.
Lee has fast clear and early pressure, but late-game is just an ult bot. Kha'zix is entirely useless late game if the enemy team has any form of peel, and while Warwick is a decent damage threat early, he gets forced to be a below-average tank late-game.
I didn't mean to start an argument, all I wanted to say is that if you pick a slower clearing champion than the enemy jungler, you'd better have a reason for it. Pick/ban strategy is a large part of the game.
P.S. I don't know what Maokai rework version you are on, but his clear is way too fucking fast for being a tank.
P.P.S. what a hypocritical statement, saying jax is a fast clear then using him as an example of a slow clear
See but thing is if you a jg with a slow clear time, say Eve, against a jg with a fast clear time, say Jax, you're gonna end up behind regardless
