I can backup Thomas that debian is typically a version behind BUT rockstable like nothing else.
Ubuntu seems faster, but (unfortuntaley) their packages are not always compatible with debian ones. They make their own package versions (same like Suse/Novell, Redhat etc.). That might not be an issue for you, for me that was a concern. F.e their Python version is not compatible with the debian one.
