Sorry, but the Joker is a bigger deal than Heath Ledger - and 'whether you like it or not', Heath Ledger was the best Joker only in yours, and probably quite a few other peoples opinion, but it's still just opinion and not some indisputable fact like you make it out to be. Personally my favourite on-screen Joker would be the guy from the Batman: Dead End short film, because his performance captured pretty much exactly how i'd always imagined Joker while reading the comics;
