But aren't all allocation styles basically the same once you get GC? (I guess unless you broaden the scope of the word, and let it describe the lengths you go in Haskell to avoid allocation at all, aka triggering stream fusion and automatic deforrestation in general.)

There are other issues: Go has stuff like slice for efficiently allocating array data more finely than a Java array, perl has autovivication.
