Robin Hobb's series, especially the ones that feature Fitz as the narrator.
The Belgariad and Mallorean by David Eddings
I don't read much fantasy, but I like the Watcher series a lot, Night watch,day watch, twilight watch, last watch.....
Terry Goodkind's Sword of Truth saga. Despite his unpolished style I enjoy his stories and characters immensely. Plus his books were the first ones that really made me start reading fantasy on a regular basis.
I also really like Kushiel's Legacy by Jacqueline Carey. Her prose is beautiful and she has excellent worldbuilding skills. Also, Barb and JC Hendee's Noble Dead series is worth a look. It combines vampire fiction with sword and sorcery fantasy; quite interesting.
Bah, forgot about Discworld! Those are so funny (most of them; The Last Continent was boring as hell).
Now if we're talking about modern fantasy, then I'll go with Jim Butcher's The Dresden Files and Laurell K. Hamilton's Anita Blake: Vampire Hunter (despite its decline in quality). Kim Harrison's books aren't too bad either . . .
