Sorry, the real problem is figuring out which 10 stories are actually worth reading, per Sturgeon's Law.
The whole point of the post is that the author has already told you what 10 stories* are actually worth reading and is now telling you which anthologies to buy to read those 10 stories.
*: Technically it is a list of 275 stories worth reading from across the entire history of science fiction, which is why there is a math challenge to figure out exactly which 22 books you needed to buy to get those 275 stories.
TL;DR: which stories to read was already solved.
