This is an interesting thread.
I'm older than dirt now, but when I was a young gunsmith, there was only IMR powders (which were made by DuPont down in Wilmington DE, and all shinny BLACK) and a very few ball powders like BLC2.
A that time, "Overbore" meant that the case size to bore ratio/sectional density, was so large that you couldn't find a powder slow enough to fill the case (now, "overbore" means any large case 
).
I am slow to change, but I welcome the new powders - the small grain stick powders like H-332, BM, and IMR-8202-XBR are great.
The short cut versions of oldies like 4198-SC, and 4831-SC have (for me) replaced the old long stick versions.
The very worst powder I ever tried to run through a measure was 4064 
I think that most of the new powders are real improvements over what we had in the past.
Pistol powders like Blue Dot and Unique were effective, but so filthy that you had to wash your clothes (on long cycle) after shooting them - now the Clays family and other squeaky clean powder are a joy to use.
Just my thoughts.
