See the apt_preferences man page for information on prioritizing
distributions.  My own preferences file contains

Package: *
Pin: release a=testing
Pin-Priority: 700

Package: *
Pin: release a=stable
Pin-Priority: 650

Package: *
Pin: release a=unstable
Pin-Priority: 600

Package: *
Pin: release a=experimental
Pin-Priority: 550

So I see packages from all of these distributions, but when
automatically selecting versions to install it prefers testing, second
choice stable, third unstable and last experimental.
