i still use it but mainly just on .22 rimfires these days. There are better solvents for removing copper fouling or heavy plastic fouling from shotgun wads but when it's just a matter of running a few wet patches down a bore followed up by dry and then a little Break-Free for a preservative, good ol' No. 9 still does the trick. I especially like it with Bore Snakes on .22 pistols that I don't like to disassemble like a Ruger or Colt Woodsman. A cotton swab dipped in No. 9 to clean the breach face and chamber/extractor cut area and you're usually good. Plus like others, the smell brings back great memories.
