I think it is rather because the arrays work vastly different, so
we're comparing vastly different things here. Let's make a test that
employs hash structures and let's see again.

I think the test was "rigged". Arrays in Delphi work very different
from arrays in other languages. This test demonstrated that for this
case Delphi's arrays work really well. That's all.
