i´ve been a Xin Zhao main since season 7. I haven´t played this game for so long compared to other League players but I think I have knowledge about the game and Xin Zhao. I started maining Xin in the Jungle when I was looking for a jungler I like and Xin won the contest. Only Warwick came close to him. Xin all in level 2 ganks is the best in the game only Lee Sin Could contest that. Xins rather easy mechanics made me like him because I wasn´t super good at micro play back then. His strongest positon is without a doubt the Jungle but if you know enough of how to play him he may also work in the toplane and midlane.

Pros:
-Excellent 1v1 Duelist with an very strong all in combo.
-Very well rounded so their is a lot of options to build on him.
-His passive makes him good at clearing the jungle and stay at high health.
-The strongest level 2 ganking potential in the game together with Lee Sin.
-Rather easy mechanics for beginners and people who ain´t that good at micro play.
-Snowballs very hard if fed.
-Good Ultimate for teamfights. E into the enemy team and R away them from each other so that they will all waist their abilites on you and you won´t really take that much damage. after that your team should take care of the rest.
-Unexpectedly good CC for ganks.

Cons:
-Very poor escape options. If you splitpush and 2-3 enemy champions are running at you there´s no point in trying to get away just stay and try and get at least 1 kill.
-Because of Xins easy mechanics. he doesn´t really have any kind of outplay in his kit. you know for a fact that when you´ll lose a traid and potentially get killed.
-You need to get that early lead otherwise you´ll have a hard time. Xin Zhao doesn´t scale super good but not super bad either. But when you fall behind early on Xin you will have a very hard time unlike jax or warwick who can just wait to late game to scale.

This is Xins strongest combo by far. I call it "The all in combo."

1.Firstly you press Q.

2. After that you E into your opponent.

3. Q your opponent 3 times so they´ll get stunned.

4. When they are up in the air W them.

This combo is what makes Xin Zhao among the strongest 1v1 champions in the game. I can guarantee that almost every champion excluding some (Jax, Viktor or Aatrox) will be belove half health after this combo. and if they are already belove half health and no flash it´s a kill.
