I think my short story, The Tightrope is my best work. It also happens to have been reprinted the most times (7 in 3 countries). It is a character/cultural study of the haves and the have nots. Like many of my stories, it has a O'Henry twist at the end.
My worst story, hmmm.. I guess it would have to be Recycling Technology, the only story that never got published. I think I was trying to be too clever (one should never be too clever).
For your personal reading, here is a link to The Tightrope, where you can also post a comment if you like.
