Another interesting point in this discussion is that, usually, benchmarks
compare the "best" programs one can write in each language, but in many
projects we do not have time/energy/knowledge to write the "best" possible
code. So, a quite useful "metric" is how easy it is to write efficient code
in a language, and/or how efficient is "average-quality" code in a
language.

There is an interesting paper about that, see
