My favorites at the moment are Jim Butcher and TA Pratt. But urban fantasy will never replace epic fantasy in my heart. George RR Martin, Daniel Abraham, Kate Elliott, Lynn Flewelling, Patricia Briggs' Huron series, Jacqueline Carey, Ellen Kushner, Guy Gavriel Kay, Sarah Monette, Greg Keyes, Pratchett, naturally. I never found an urban fantasy series to get even close in quality (writing, plot, characters, ideas) to epic fantasy.
