I won't say which is better. In fantasy, I am close to the well-known Tolkien, although I am more of a "dark Tolkienist" than a "light Tolkienist."
In science fiction: it's the great Lovecraft. I have been reading all his works in a row for a long time, and I can say that I have never been disappointed. Except that "The Call of Cthulhu" is a bit overrated.
IMHO.
