I don't remember the conclusion either, but I definitely remember the discussion. I'm sure it was probably discussed in this thread way back when it was new.
The most interesting thing about that for me is that Astro is having them made in Asia, but manufacturers have begun producing this design in the US as well. That kind of flips the stereotypical design/manufacturing work flow (USA company creates product, Asian manufacturer copies design and produces a cheaper version for import) on its head.
To be clear, I have no firsthand knowledge of any of this and I'm essentially parroting what I have read here on the forum, so please take all of this with a grain of salt.
In any case, I have the set I got from Astro when they first came out and I use them regularly. I find they produce rounder holes and less exit burr on sheet metal, and the step tips sort of act like pilots when enlarging existing holes. Those features alone are enough for me to keep them around.
Chris has said here before that if you call them you can order individuals or a set of the smaller bits but it would be great if they had a set of just 1/16" through 1/4" available as a standalone item on their site. Something like
this but without the fancy case.
