Which is better CAD or BIM?

I'm curious to know which technology, CAD or BIM, is considered superior in the field of architecture and construction? CAD has been a staple for years, but BIM seems to be gaining popularity lately. What advantages does BIM offer over CAD, and what are some potential drawbacks to consider? How do these technologies compare in terms of efficiency, cost savings, and collaboration among team members? Could you provide some insights into these aspects to help me make an informed decision?
