If you are speaking as to the quality of the brand, they are just as good as 
the ones made today. There are better ones out there that employ the use of 
advanced coatings and materials.  The grinding of the point may have changed 
as well as the flute design. All of these advancements are generally geared 
toward production machining and have no benefit or do not work well on 
simple machines/setups. Large runs permit you to cherry pick special 
features and gain time and quality. Some manufacturers have products so use 
specific it is only stocked at the factory.
