Favorite and least favorite mid lane champ to play?

So to all the mid lane "gods" out there i want to know who do you enjoy playing in the mid lane? And i don't want your answer based off how easy it is to win with said champ or how you have won most of your games with this champ. I want to know what champ is the most fun for you and what champ is least amount of fun to play.

My favorite =

Least favorite =

I enjoy Lulu so much because her kit is just so cool in my eyes, I find her the most easy to farm with because of pix and i enjoy how you have just so many options with all of her abilities. I've had clutch situation where i was dived by an and i popped my E on myself and ended up surviving while getting a free kill. Then you have her ult which i enjoy the most for the simple fact having a ulted in a team fight is just stupid and funny. She also looks beyond cute in her pool party skin.

Azir is my least favorite because i do not like his kit that much, his entire kit is based off his soldiers and i don't exactly find that fun. Plus i'm tired of getting poked out of lane because of him.... >.> But my anger aside i can understand why people enjoy him, i just don't.

So there is my favorite and least favorite with my stupid reasoning behind them like all ways and now i want to know your guy's picks.
