I do not think your taste is critical if you enjoy Game of Thrones prose. Gene Wolfe's is far above. GoT is average fantasy prose and nowhere near literary fiction quality.
Story and character is more important for me than prose. I need to care about what is happening to want to read on and I found the book of the new sun wanting in that regard. I found it a struggle to read - similar to the storm light series (which I found even worse with paper thin characters and terrible plotting).
Just my personal opinion.
