Lee Sin or Jarvan IV?

Just save up for Vi. Or buy Sejuani.

lee is more fun j4 is more reliable both are good tho

J4 is far better in general, don't listen to the whiners who complain that Lee is op, at least in solo queue. The reason J4 is better is his cc, and this makes him not fall off later. He has good single target lockdown, and his ult is great in combination with an aoe mage.

Lee has a pretty good early game, and slowly gets weaker in strength. He has ok cc, but it's really only useful if you can insec someone, which is much harder then the pros make it seem. Overall it's up to you, play the one that you have more fun with, but from an objective standpoint, J4 is far better for solo queue. I hope this helped!

If you wanna get good Lee is gr8. I don't feel like typing an essay on why I'm a Lee Sin main but do it, it's fun
