The best champion in the game

I have often though about who is the best champion in the game. While many will say the all champs are equal most people know this is not true. I understand that all champs supposedly have counters but that does not mean there is not a best champ. Personally I believe that the best champ is 1 of these 3 champions.

1. Fizz- He has built in zyonas, great mobility, great damage, and is overall full of bull. I think everyone knows why he is op. 2. Olaf- I don't think Olaf is considered to be as op as he is. He can out auto attack 99% of all champs. He has a good poke, great lifesteal, epic attack speed, true damage, and can block all cc with his ult. Olaf is nearly impossible to counter. If you build armor he kills you with true damage. If you dont he kills you with auto attacks. If you build health he builds blade of the ruined king. He is nearly impossible to counter build 3. Yorick- Some people say that yorick is really bad. They have never played him or against him. He has a great slow, he can speed him self up, has great sustain, he can deal impressive physical and magic damage, has a great poke, and can 1v1 nearly anyone with or without his ult. He is nearly ungankable, nearly impossible to chase and harder to escape from. And i have not even gotten to his minions yet. A joke i often say is yorick walked into a bar. There was no counter. This is pretty much true. He is a god laning phase and nearly as good late game.

Please tell me what you think. If you believe the best champ is someone else please say who and why.

Edit: Other champs i think might be the most op are Akali- Insane burst, Op sustain, Invisablilty, and good moblilty Katarina- No mana, Op scaling on ult, great poke, good moblilty heimerdinger- turrets
