Under ARC there should be no appreciable difference. People who prefer
+new will generally point out it's a keyword or operator in other languages
so its meaning is not ambiguous.
With manual reference counting, the difference is that +array is
autorelease where as with +new your code is responsible for releasing the
object. Some projects used to discourage the use of +new as it was one
less selector/function name to memorize (i.e. copy, alloc, create..., new).
