You know, they have different styles. It is even possible to like both TWOT and ASOIAF!
Both require some patience in that books 4 and 5 of ASOIAF have slowed in excitement and the series is far from finished, while TWOT is a long series with quite a lot of criticism of books 7-10 (though some people still love them), but very well received early and later books. Both have a lot of details. TWOT has more magic and is "high fantasy" where ASOIAF is more concerned with plots and intrigue. Both have a lot of praise overall. Whatever Fantasy series/book you pick some will criticize it.
I would definitely go along with Steven Erikson's Malazan series being another to consider, as well as Stephen King's Dark Tower series. Again, both have different styles.
