Best Jazz pianist

Who's the best Jazz pianist, or your favourite.
Chick Corea (when he ws young); Art Tatum, Lyle Mays, and I would add some non-jazz folks as well, including Evgeny Kissin.
+1 for Brad Mehldau, how about Esbjorn Svensson (EST), Aaron parks, Renee rosnes, Kenny Werner, Sam yahel (well, organ), wessell Anderson, craig taborn, mulgrew miller. Vijay iyer, Fred Hersch, Robert glasper, so so many!
