Zed or Yasuo?

Potato.

I like zeds laugh, thats about it. Kappa. Both are good, but I vote yasuo.

I don't like playing either one of them; they don't really fit my preferred playstyle.

I'm not really a fan of having either one on my team. Depending on when they were picked, they could have easily messed up our team composition or resulted in us lacking magic damage and/or CC. I find that they tend to attract certain types of players (attitude wise) and people generally can't play them competently anyways.

However, I really enjoy having Yasuo on the enemy team. If he's against me in the top lane, most of my picks have favourable match-ups against and him and snowball off of him rather easily. If I'm jungling, Yasuo is squishy, lacks reliable escapes and has to play aggressively in most match-ups, so he's a very easy target to gank and kill.

In short, I prefer Yasuo.

They feed me so I can grow big and strong.
