And maybe one more point - if any of the two languages was better in all
    cases, then how would you explain, that the other one still survives ?

Please repeat to yourself, over and over again until you are convinced,
"having the fastest possible most efficient code is not always important."

As an extreme example, I think I can state "assembler is always faster than
interpretted pbasic" without much fear of contradiction.  That doesn't mean
that there is no reason for the basic stamp to exist...

Sometime, I shall have to tell you all my views on why cisco had to abandon
horizontally microprogrammed bit-slice microcontrollers as their preferred
engine for network controllers.  If the reasons aren't obvious :-(
