Best Jazz pianist

My favorites are Horace Silver, Monk, Herbie Hancock.

Although I selected one above I agree with HiFiHarv's statement "How can there be a best" The arts are not a competition. All musicians have something to offer you. It is up to you to decide whom you like

Thelonius Monk & Keith Jarrett are at the top of my list.

Surprised McCoy Tyner hasn't been mentioned yet, but he is another great one.

It would more imformative and allow for more complete posts to ask, Who is the worst Jazz pianist? Because all the players mentioned are great, and I'm sure no one named all the ones they could have named.
