Query: Best Year's Best SF in Years

I have been reading Year's Best book from Year's Best SF 3. I was somewhat disappointed with stories in SF 7 and 8, but SF 9 delivers extremely interesting and thoughtful stories. I really enjoyed stories by Gene Wolfe, George Benford, and my favorite "Four Short Stories" by Joe Haldeman. Buy and read this book, you will not be disappointed.
