other Veteran vs new actors: who actually acts better?

[Dr. A]

A lot of people grew up knowing names like Sylvester Stallone and Arnold Schwarzenegger as real macho, heroes who probably were the trendsetter for the use of heavy weapons. Years have passed and new faces have dominated the acting industry. Few latest releases like the Armor and Sly has tried to rekindle the love for those heroes once again. However, with rusted acting skills and older age, do these veteran actors still have the same impact on their audience or are they just losing their once-gained-fame further by displaying inferior acting skills than the younger generation actors?
