Yes, you want both, but the question was whether to prioritise builders for ziggurats over campuses.
Actually, they don't really compete.
In early game, you may well do that, but a city you fond later on you can rush the campus buildings with gold so it's more efficient to build the campus.
Builders can be rushed or built form another city, so the two features d'ont really compete:
Early on:Ziggurats (you can't do districts anyway).
When you can: Start building campuses.
Late cities: Campus locally, builders remotely for ziggurats and gold to buy buidlings or local builders.
