The former, if indeed new, by their marking seem to be mil grade Soviet ones which were always good. They would come of the same production line as the rest of them but would be held to a higher standard. The other tubes could be as good but were not tested to these standards.
The latter are not Soviet, they are Russian and are supposed to be good tubes, but as their manufacturing was stopped for over 30 years, they are probably not exactly the same. Maybe better. Maybe not.
Personally, I bought mil grade Mullards for my Mac. The best Soviet tubes, however good, never bested Western manufactured ones.
And, this said, I am honestly not sure I would be able to hear the difference.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
