Taraweeh in Congregation and Congregational Prayer in Last Third of the Night – Shaykh Baaz

If a Muslim prays with the congregation, in Ramadhan, the Taraweeh prayer and there is also a prayer in the last third of the night, then which of the two is better and takes precedence? To perform the witr with the congregation and make the witr even, or should he leave off the witr with the congregation and pray the witr in last third?
