I've done a little timing of things, and according to my results:
If you care about efficiency and use OCaml, you should use lists 
fairly often, ie if you are always looping and accessing the elements
in order. OCaml can iterate through a list (recursively) about twice as
fast as it can iterate through an array.  It can iterate through a 
list about as fast as or maybe even a little faster than C or C++ can
iterate through an array.
