Full factorial designs are, as the name suggests, the combination of every factor at every factor level. Full factorial designs can be very expensive in terms of the number of runs needed to set up, but when you have few factors with few levels, and you are not constrained by throughput or cost, these are very powerful designs.
When you have the resources and throughput, often a full factorial design can be the most powerful choice. Learn more about full factorial designs here.
While full factorial designs can be the most powerful, there are some edge cases. Learn about the statistics behind full factorial designs and why sometimes even these require replication.
