When should you use a Star and when should you use Snowflake Schema

Q: When should you use a Star and when should you use Snowflake Schema ?

Star Schema :  If the performance is the priority Than go for Star Schema, Since here dimension tables are denormalized.

Snowflake Schema : If memory space is the priority than go for Snowflake Schema, since here dimension tables are normalized.
