SQL 2012 :: Index Maintenance And Update Stats

I am using Ola Hallengrens scripts for index and stats maintenance but I am wondering what most people to in terms of the maintenance schedules. At present we do an index rebuild reorg weekly, but do people also do update stats nightly?

I suppose there is an element of "it depends" here in that the data may be fairly static so the update stats may not be required, or if heavily updated then perhaps rebuilding indexes may be required more frequently.
