PoolManager manages instances more efficiently to increase performance, organize the scene hierachy and is simple to implement. When an instance is needed over and over why destroy it? Re-use it! PoolManager has many additional features, such as preloading, to help you develop and run your game faster.
Now for Unity4 for the fastest PoolManager yet! Supports Shuriken Particle systems to offer auto-despawning when all particles die.
