Chez's GC is a lot more configurable, and the default is smarter, than either Gambit or Chicken. Chez has a generational garbage collector, rather than the more simple ones. It can also run in parallel mode, to prevent it being "stop the world" - it'll run in another thread instead.

Because the collections are smaller, and you can slightly offload them into another thread, it's a lot less noticeable in usage.
