That people use standard collection classes more often than in these benchmarks where they little used (if at all) is a big fat assumption?! There are going to be many situations where using a primitive array is not the right choice. When you need a hash table, a set or an expandable array, for example. If you are claiming that these benchmarks are indicative of the real world, you are claiming that collection classes are not used in the real world, since hardly any (if any) use the built in collections.
