Who's stronger ATM. Yi, vi, or Xin Zhao

I want a jg that can solo carry and be useful all game. I was a shyvana main for 2 years and it just seems like she just falls short and when she is strong, riot nerfs her and pretend she doesn't exist and nerfs her items since they are broken af on other champions. It's likely ke they won't allow her to be good due to how simple her kit is. It's just like urgot when he was playable in s5 and then the nerf hammer. I actually bought him because in 3 patches is the urgot rework most likely. Shyvana's biggest issue is while gankng jg's are feeding their lanes, she's stuck farming. If they pick some who ganks only, your up shit creek without a paddle. Yes the means you're paddling through the shit with your hands, oh excuse me, claws. The meta has shifted to utility jg's but they just aren't that fun. I want something that's fun and easy to play and can still solo carry. Yi is the pentakill god but is super greedy and just ganks for himself mostly and the you mains are salty af. Still doesn't beat vayne, yasuo, or riven mains. Xin Zhao is a dueling good much like shyvana. He takes so.e time to ramp up and he has slow clears since he mostly uses aa's and he single target. VI can farm fast and gank early. Her ult is a good dive tool. She also like shyvana can shred tanks. But when you dive, you need to get the kill him r you just fed a free kill. So who's stonger ATM.
