Champ I hate and love at the same time

Do you have any champion you are really good at? I'm not a very good player but I enjoy playing Teemo a lot, what's funny is I also hate playing against a good Teemo player. the things I love about this champ are mostly the things I also hate. If Teemo is well fed and built pure AP, his mushrooms would definitely eat up a lot of your HP, not to mention his Q that hits like a truck. Does anyone here have this thing too?
