I also used to find indices more readable, but after using iterators almost
exclusively for a couple of years, that no longer holds true.

As for compilers generating equivalent code, that hasn't been my personal
experience. The last time I benchmarked equivalent scenarios, iterators
and pointers were both substantially faster than indices, even on CPUs with
hardware math acceleration.
