I'd say they are your typical bar stool.  The assembly was pretty self explanatory.  The screws go in a threaded sleeve that's about it.  The stools are okay.  I wouldn't say they were anything to write home about.  They were priced just fine.  I don't think they are over priced.  Personally, I think they are a little small.  As for a rating.......I'll just leave that up to you.
