Reusing objects will always going to be faster. If memory is not being allocated, GC never runs.

Look what happened to Minecraft when they stopped caring about allocations: http://what.thedailywtf.com/t/optifine-modder-rips-the-minec... It's allocating 150 MB/second. It's now much slower than it was before.

With new allocations you can have better cache consistency, so reusing objects is not always faster.
