Fantasy isn't very fantastic without magic. Faeries, Elves, Wizards, and what have you. Wizards tend to be very powerful magical practitioners, and can effect a story greatly. Can't make them TOO powerful, but can't make them too much of a joke or else they are... I don't know, maybe a magician? Something undesirable, anyway. But often wizards are the best characters! Anyway, let's get down to business.
For me personally (beside Gandalf) I would have to say Merlin and Schmendrick are tied. Merlin is the original badass, but Schmendrick is a lovable ponce with potential, and I have read The Last Unicorn more times than Once and Future King (yes some call him a magician, but in my heart I believe him to be a wizard by the end.)
So who is your favorite Wizard? And why?
, he's a great character with understandable motives and its great he doesn't get sentimentalized like other characters. And yes i admit he also is a tool like Gandalf, in fact much worse than Gandalf but at least he's not disingenuous 
. Right from the start you know he'd sell you down the river in a heart beat and its nice to know where one stands
